The above results are from Zygo interferometer. If you need other specification reports, please contact us, we will always be here to support you. 

 We can also manufacture custom made lenses as your request strictly .
-Meniscus lens                                         -Achromatic Lens
-Bi-Convex Spherical Lens                          -Bi-Concave Spherical Lens  
-Plano-Convex Spherical Lens                     -Plano-Concave Spherical Lens
Usually some customers confused that why the unit price change so seriously with the quantities. The following example will show you the reason.
In the polishing process the products(not polished windows and lenses) should be fixed on a plate and then assembled into the polishing machine. Sometimes the lenses have a suitable dimension and radius that can be polished several quantities in one time as the picture showed. But sometimes the lenses with too small radius or too big radius caused that just can polishing one piece of lens in one time.  
 
All of the lenses have to be fixed on a plate for polishing. The plate must to have the same radius with the lens. Jiheng Optics have more than 3000 pairs of plate and more than 3000 pairs optical plate. This can save you lots if we have the plate can be matched as your request. 

Jiheng Optics can supply the optical plate list to you, please contact us.when you need it.
