Micro Lens (Ultra small lens)
Because of the ultra-small size of this kind of lens (outer diameter 0.5mm-5mm, length: 1mm-20mm), micro lens or ultra-small lens often requires special processing technology, unique production know-how and special optical fixture, etc.
Photonchina provides various sizes of micro lens with an array of applications including active devices, wavelength division multiplexer ( WDM) and fiber lasers (see C-lens, G-lens) in fiber communications, endoscopy for medical and industrial use, capsule endoscope, etc. Its new application fields are still expanding.
A variety of optical glass or other materials, such as N-SF11, H-LAF76, Fused Silica and so on are available for customerâ??s design. H-LaF53, for instance, has often been used in endoscope lens or capsule lens production. The outer diameter of micro lens covers 0.5mm to 5.0mm with any radius of curvature that can be made. We have a wide range of lenses in shape: convex, concave, biconvex, meniscus etc.
Photonchina can provide unique rod-shaped glued lens by combining special gluing technics and edging skill. This rod lens has excellent eccentricity and clear aperture index. From design, manufacturing to optical coating, from endoscope lens, capsule lens to special-required rod lens, engineers in Photonchina implement strict production process to ensure stable quality, good yield, competitive price as well as responsive lead time.
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.

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.
