Optical lenses are transparent components made of one or more pieces of optical-quality materials (ground and polished or molded) and curved (always spherical) to converge or diverge transmitted rays from an object, These rays then form a real or virtual image of the object.
O.E provides spheric lens, aspheric lens, cylindrical lens and achromatic lens with a wide range of sizes and materials including N-BK7 ,H-K9L, Fused Silica, N-SF5, Sapphire, CaF2, Silicon, Germanium, etc.
Optical Spherical plano-convex/ plano-concave/ Double-convex/ Double-concave/Meniscus Lens with Anti-Reflective(AR)/High-Reflect!ve(HR)/Partial-Reflective(PR) coatings
O.E provides five kinds of spheric lens forms, or shapes, that determine the imaging Characteristics of the lenses, they are plano-convex, plano-concave ,Double-convex, Double-concave and Meniscus.
• Plano-convex lens has a positive focal length, which makes it ideal for collecting and focusing light for many imaging applications..
• Plano-concave lens has a negative focal length and is used for image reductinon or to spread light
• Double-convex lens has a positive focal length and is useful for 1:1 imaging and in multielement systems, also known as biconvex or equicon vex.
• Double-concave lens has a negative focal length and is useful for 1:1 imaging and in multielement systems, also known as biconcave or equiconcave.
• Meniscus lense has a positive or negative focal length, it forms a real or virtual image of objects.
Note for Spheric Lens:
(1) . Other optical glass materials from Schott or Chinese CDGM are also available upon request.
(2) . Custom-made Spheric Lenses at any size from diameter 2.0mm to 300mm are available upon request.
(3) . Typical paraxial focal length tolerance is ±2%, better tolerance is available upon request
(4) . Typical centration is 3 arc minutes, better precision is available upon request.
(5) . Besides uncoated, Lenses with Anti-Reflective(AR), High-Reflect!ve(HR), Partial-Reflective(PR) coating
are available upon request
