Micro Spherical Lenses
Under the condition of high refractive index, some optical components can achieve short focal length. Therefore, the micro lens becomes an ideal choice in the field of high precision applications.
Through years of accumulated processing know-how technologies and production capacity, high standard thin film coating performance and strict testing requirements, Photonchina provides customers with one of the world's smallest but excellent micro lenses products, which have been widely used in various medical devices (endoscope lens, for example), precision surveying and optical communications instruments.
From design, manufacturing to optical coating, from endoscope lens, capsule lens to special-required rod lens, from single mini lens to glued lenses system, engineers in Photonchina implement strict production process to ensure stable quality, competitive price as well as responsive lead time.
A variety of optical glass or other materials, such as BK7, N-SF11, H-LAF76, Fused Silica and so on are available for customers design. H-LaF53, for instance, has often been used in endoscope lens or capsule lens production. We have a wide range of lenses in shape: convex, concave, biconvex, meniscus etc.

The Powell Lens can be widely used in alignment, machine vision systems, construction and process control fields.
Worldhawk are professional supplier for powell lens, in fact, we have already become the one of the main important suppliers of powell lenses in China. cooperation with us , you will get high quality products with reasonable price and products performance at the same time
These Laser Line Generator Lenses, also known as Powell lenses, generate a straight, uniform laser line by fanning out a collimated beam in one dimension, as shown in the diagram above. The apex of each lens features an aspheric curve that evenly distributes the optical power, resulting in an intensity variation of less than 25% over the center portion of the line. You will get more even energy distribution along the laser line than using the rod lenses and lenses.
Photonchina produces the smallest rod lenses for customers at home and abroad.
Micro rod lenses: 0.5-1.8mm diameter, 1.0-25mm length, with one end of designated curvature radius and another end of arbitrary angle.
Both ends of arbitrary radii or angle are also available. Highly customized products for a wide range of applications from medical device, fiber communications, optical display and surveying equipment.
What is more, we can provide unique rod-shaped glued lenses by combining special gluing/cementing technics and edging skill. These glued/cemented rod lenses subassembly can be made of up to four single micro rod lenses with various combination. Rod lens assembly systems are able to provide images with greater brightness, contrast and color reproduction than conventional lenses.
Rigid endoscope, for instance, which usually has a series of high-resolution optical glass rod lenses, can be forward viewing (0 degrees) or angled (10120 degrees) to allow visualization out of the axis of the telescope and increase the FOV by rotating the instrument. The optical quality of lens-generated images of rigid endoscopes still surpasses that of the fiber-optic or digital images produced by flexible scopes.
High performance optical coatings for rod lenses are provided.
Optical glass material NBK7, N-SF11 from Schott, Corning 7980 etc, are all available.

Optical Lenses are optical components designed to focus or diverge light. Optical Lenses, which may consist of a single or multiple elements, are used in a wide variety of applications from microscopy to laser processing.
Worldhawk can supply Plano Convex Lens, Double Convex Lens , Plano Concave Lens, Double Concave Lens, Meniscus Lens, Achromatic Lens and aspheric Lens.
Optical glass lenses have a wide variety of applications. Germanium (Ge), Silicon (Si), or Zinc Selenide (ZnSe) lenses are ideal for transmitting the Infrared (IR) spectrum, while Fused Silica is well suited for the Ultraviolet (UV).
Low Tg Ball Lens has the characteristics of low melting and softening temperature, being easily shaped and special optical-mechanical properties, easy to be molded by secondary pressing, suitable for precision pressing of aspherical lenses, which helps to reduce the production cost of batch lenses. Low Tg Ball Lens / Aspherical Lenses are applied in precision molding, such as digital cameras, video cameras, mobile phones, etc.
