Description
Under the condition of high refractive index, some components can achieve short focal length. Therefore, the micro lens becomes an ideal choice in the field of high precision applications.
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 customer’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.
