Product Description

12.7mm Diameter Schott N-BK7 Uncoated Plano-Convex Lenses

Spherical Lenses

Optical lens are used to converging or diverging the light, it is widely used in microscopy, laser, image, light etc. So it requires different materials for different work range. CPG optics handle from UV Materials from deep IR materials. With our closely QA process, each lens is guaranteed for all your needs.

In some meanings, we can say, each elements in optics can't work with coatings, so CPG also provide different coating for, from mental to dielectric, surely CPG will be your best choice.

 

About Super Polish

CPG optics provide a super polish product, aimed to help our customer to win more in the market, we developed this kind of cross-border fabricating method. it combined with a different process from different industries. of cause CPG won also followed our customers.

Super polish also means for the RMS(Ra) control of the surface quality, we could control the RMS to 1 angstrom, we are very please to help our valued customer to process the mass production of the products. 

Our super polish windows now is widely used in Mirau interferometers, and for 635nm high energy laser application, our products showing a more stable and long working times.
