OST Photonics Cylindrical Lenses Cylindrical lenses are utilized for astigmatism correction in the eye and rangefinders, inducing astigmatism by elongating a point of light into a line. They find extensive application in barcode scanning, projection optics systems, laser measurement systems, and holography. Ost Photonics offers cylindrical concave lens in plano-concave or plano-convex configurations.

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.

A Telecentric lens is a kind of lens that the chief rays are parallel to the optical axis. There are three kinds of telecentric lens, that is the object-space telecentric lens, image-space telecentric lens, and the bi-telecentric lens. Telecentric lens is always the core business of� Canrill Lens. After continuous research and development for 11 years, Canrill has successfully developed 1700+ kinds of lenses, and the number is still increasing, to meet the diverse and growing applications at the best telecentric lens price. Difference Between Object Space Telecentric Lens And Bi Telecentric Lens Telecentric lenses have two types of telecentricity: telecentric objective space and image space telecentricity (referring to the entrance and exit pupil positions, respectively). Therefore, telecentric lenses are divided into: object space telecentric lens, image space telecentric lens, and bi telecentric lens. Object Space Telecentric Lens In general, a machine vision telecentric lens refers to an object space telecentric lens. If the entrance pupil of the lens is located at an infinite position in the image side (all objects behind the objective lens), it can be called an object space telecentric lens.� The chief ray originated from optical axis is parallel with optical axis in object side ( or to say have very small angle �¸ which is called telecentricity in telecentric lens specs), while in image side is not parallel. china bi telecentric lens with entrance pupil projected to infinity on the image side In the optical design, object space telecentricity is achieved by placing the system's iris diaphragm at the intersection of the front-end groups. Since the entrance pupil is at infinity, the field of view is constant and has no field angle. Since the chief ray (which defines the system's field of view) passes through the optical axis at the aperture stop, when the pupil is at infinity, the ray is parallel to the optical axis and the field of view is zero. By contrast, any entrance pupil within a finite distance of the lens results in a non-parallel fiber.
