The surface polishing quality and coating of these lenses are excellent and will work for 755nm and 1064nm or both 755nm &1064nm.
Laser manufacturers use the focus lens in order to adjust the size of the laser so it can travel from the laser head, to the fiberoptic, the handpiece and finally reach the patientâ??s skin. It is very important that the focus lens are spotlessly clean, free of dust and scratches. Dust and scratches on their surface will cause the laser to burn them gradually, prevent full laser emission, and can misdirect part of the laser, which can cause other components to be burned. We strongly recommend keeping the focus lens in good condition. Additionally, keep your work area spotlessly clean in order to avoid dust particles which can be detrimental to aesthetic laser equipment.
These are premium and quality custom made focus lenses that are made exactly by the manufacturers requirements. These focus lenses have been applied with AR coating to achieve optimum durability and transmitting of the laser beam. This will create better treatment results and allow your machine to be more time efficient.

Overview of Silicon Lens
Silicon lenses are widely used in infrared applications, requiring optical elements with high thermal conductivity and low weight. Silicon plano-convex lenses are ideal for optical systems that collect, focus, or collimate light in near-infrared, short-wave infrared (SWIR), medium-wave infrared (MWIR), or long-wave infrared (LWIR) spectra.
Features of Silicon Lenses
Excellent Light Transmission:
Silicon lenses have high transmittance in the visible and near-infrared spectral ranges.
High Refractive Index:
Compared to other materials, silicon lenses have a higher refractive index, which can effectively reduce the thickness of the lens.
Spherical Lens
Spherical lens, also known as a single lens, is an optical lens with a curved surface that converges or diverges light. They are widely used in imaging applications. Conjugate ratio, lens shape, radius of curvature, lens material, transmittance, wavefront aberration, scattered light, and type of coating are all features that must be considered when selecting a lens.
Types of Spherical Optics
There are two main types of spherical lenses: concave and convex. Concave lenses are thinner at the centre and thicker at the edges, while the opposite is true for convex lenses. At HS Optics, we routinely produce both types of spherical optics for a variety of imaging applications. The different formats we produce include:
Poly lenses are called convex lenses. It is thicker at the centre than at the edges. Convex lenses come in several shapes and sizes depending on how they look and work:
1. Plano-convex lenses
2. Double-convex lenses
3. Meniscus lens (concave-convex lenses)
Concave lenses. Thinner at the centre than at the edges. Concave lenses can be classified as follows:
laser optics windows are essential components used to separate different environments, such as the interior and exterior of an instrument, thereby protecting internal devices. These basic optical elements do not alter magnification but do influence the optical path. Key parameters for optical windows include light transmittance, surface accuracy, thickness, parallelism, and substrate material. Bena Optics provides high-precision windows made from various materials, including zinc selenide, germanium, silicon, barium fluoride, and calcium fluoride for infrared applications; fused silica and sapphire for spectral bands; and K9 glass for visible light. They maintain a large inventory of standard products and also offer custom optical windows tailored to specific needs.
Key Features of Optical Window
Optical windows possess high transmittance, hardness, erosion resistance, low thermal expansion, and minimal absorption loss, ensuring stable performance in various environments.
Made from materials like UV fused silica, quartz, infrared crystals, and optical glass, they offer excellent light transmission, high-temperature resistance, corrosion resistance, and electrical insulation. UV fused silica, for instance, has over 93% transmittance across the UV to IR spectrum.
Widely used in aerospace, laser systems, scientific research, and detectors, optical windows protect internal components and isolate external environments while maintaining high transmittance for specific wavelengths.
The Applications of Optical Window
Optical windows protect optical systems and sensitive electronics from external environments. Made of polished optical glass, they allow light transmission while isolating physical environments.
Optical lenses are essential elements in many optical components, primarily used for imaging, focusing, collimating, and diffusing beams. They affect the wavefront curvature of light and can either converge or diverge light, producing real or virtual images. These lenses are widely used in high-tech fields such as security, digital cameras, high-power lasers, and optical instruments.
Bena Optics currently operates two machining systems: high-speed polishing and classic polishing. High-speed polishing is mainly used for batch commercial products, while classic polishing is employed for repairs, large sizes, specific material requirements, and other special circumstances. Additionally, classic polishing serves as a pretreatment for aspherical surface processing. This dual approach allows Bena Optics to meet diverse customer needs and maintain high-quality standards across various applications.
Key Features of Spherical Lens
A spherical lens has a uniform curvature across its surface, making it widely used in optical devices like telescopes, microscopes, and camera lenses. Key features include:
Uniform Light Refraction: Acts as a collection of infinite prisms, providing uniform convergence and divergence of light, enabling image formation.
Imaging Quality: Spherical lenses have spherical aberration, where light passing through the center and edges focuses at different points, limiting high-precision imaging applications.
Application Range: Due to low cost and simple manufacturing, spherical lenses are widely used in various optical devices, especially in low-cost consumer products.
Additionally, spherical lenses are uniquely applied in coupling between optical fibers, lasers, and detectors, and in collimating fiber beams in dense wavelength division multiplexing (DWDM) systems.
The Applications of Spherical Lens
Spherical lens is used for in various optical devices for focusing, collimating, or expanding light, and forming images. Their applications span metrology, microscopy, aerospace, medical technology, laser systems, and security.
A plano-concave cylindrical lens has curvature in the vertical direction, functioning as a concave lens, while having no curvature in the horizontal direction. It is used to magnify a beam in a single direction, such as transforming a laser beam into a line or sheet of light, or altering the height of an image without changing its width. When combined with a concave cylinder lens, it can be used to shape the elliptical beam of a semiconductor laser into a circular one, among other applications.
Features of Plano Concave Cylindrical Lens
The cylindrical concave lens forms a diverging line-shaped virtual image and is primarily used to control the size of a beam in one direction. This lens consists of a flat surface and a concave cylindrical surface, with a negative focal length. Light passing through the axial meridian does not experience a change in convergence, but light passing through the refractive meridian does experience a change in convergence.
Applications of Plano-Concave Cylindrical Lenses
Beam Shaping:
Plano-concave cylindrical lenses are often used to convert collimated laser beams into line beams. By orienting the curved surface of the lens towards the light source, spherical aberration can be minimized, thereby achieving beam shaping.
Image Shaping:
A pair of plano concave lenses can be used for image shaping, particularly when it is necessary to shape a point source in one-dimensional direction.
Laser Scanning Systems:
In laser scanning systems, about plano concave lens are used to adjust the beam shape to meet scanning requirements. They can also be combined with other optical elements to achieve complex beam shaping functions.
Spectral Analysis:
During spectral analysis, plano-concave cylindrical lenses are used to adjust the divergence or convergence angle of the beam to meet different measurement needs.

What Is a Cylindrical Lens Used For?
Cylindrical lenses are specialized optical components used primarily to correct astigmatism, a common refractive error in the eye. Unlike spherical lenses, which have the same curvature in all directions, cylindrical lenses have curvature in only one direction. This unique property allows them to focus light into a line rather than a point, making them ideal for applications requiring precise control over light direction and focus. OST Photonics, a leader in cylindrical optics, offers high-quality cylindrical lenses designed to meet various optical needs.
Plano Concave Lens
A plano-concave lens is an optical lens with one concave and one flat surface. It has a negative focal length and can be used for light projection, beam expansion or to increase the focal length of an optical system.
Plano concave lens bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length. The spherical aberration of the plano concave lenses is negative and can be used to balance aberrations created by other lenses. Similar to the plano concave lens, the curvature surface usually faces the largest object distance or the infinite conjugate to minimize spherical aberration.
Applications
1. Plano-concave lenses are commonly used to divert parallel beams in instruments such as Galilean beam expanders or telescopes.
2. Plano-concave lenses are also used for beam expansion of high peak power pulsed lasers. The incident beam will be focused on a concave surface to a point outside the instrument.
Ball Lenses
Ball lenses are spherical optical components, typically made from glass or other transparent materials. These glass ball lens used primarily for focusing and collimating light in a wide range of applications, including fiber optic communications, endoscopy, microscopy, optical pick-up devices, and laser measurement systems. The simple geometry of the glass ball lens allows for minimal light deviation and aberration, making them highly effective in coupling light between fibers or focusing light into a small area. Their efficiency and compact size make fiber ball lens indispensable in precision optical instruments and devices requiring high-quality light transmission and focusing.
Types of Ball Lenses
Optical Ball Lenses
Ball lenses focus and collimate light, essential in fiber optics, microscopy, and laser alignment, offering minimal light deviation.
Half Ball Lenses
Half ball lenses offer precise focusing and collimation, ideal for enhancing optical performance in imaging and sensor applications.
How Do Ball Lenses Work?
Ball lenses function by refracting light as it passes through their spherical surface, focusing or collimating the light rays. Their geometry allows for minimal optical aberration, making them ideal for coupling light into and out of fibers. When light enters a ball lens, it bends towards the lensâ?? denser medium, converging at a point on the opposite side. The precise focal point depends on the lens materialâ??s refractive index and the diameter of the ball lens, enabling applications in fiber optics, laser collimation, and optical instrumentation.
Aspherical Lenses
Aspherical lenses are advanced optical components designed to focus or collimate light without the spherical aberration common in simple lenses. By having a non-spherical shape, they efficiently correct for optical distortions, allowing for better image quality and tighter focus of light beams. This makes aspherical lenses invaluable in applications requiring high precision, such as in laser systems, imaging devices, and optical instruments. Their unique design enables compact, lightweight optical assemblies, enhancing performance in a wide range of technological and scientific applications.
Types of Aspherical Lenses
Asphere Lenses
Asphere lenses minimize spherical aberration, enhancing optical performance for sharper imaging and efficient light focusing in compact designs.
Precision Polishing Aspherical Lens
Precision polishing of aspherical lenses ensures superior optical clarity and accuracy, critical for high-performance imaging and laser applications.
IR Asphere Lenses
IR asphere lenses optimize infrared light focusing, improving thermal imaging and laser system performance with minimal aberrations.
Parabolic Mirrors
Parabolic mirrors focus light into parallel beams, eliminating spherical aberration, ideal for telescopes, solar collectors, and high-intensity applications.
Achromatic triplet lenses minimize Seidel aberrations, usually by gluing three lenses together or mounting three lenses in a housing. Suitable for measurement and imaging applications such as projection, photography, fluorescence microscopy, image relay, inspection, spectroscopy, etc. After milling, fine grinding, grinding and polishing, the single lens in the glued lens can reach the optical surface accuracy â?¤0.1 micron, and the surface roughness Raâ?¤0.01 micron. The three lenses are glued to three lenses, and the achromatic triplet lens is glued by using a centering device with a curing device with UV photosensitive adhesive for precision bonding and eccentricity testing.
