Thorlabs Optical Lens Production

http://www.thorlabs.com/newgrouppage9...

For in-house spherical and aspherical optic production, Thorlabs has Satisloh grinders and polishers, a Satisloh C-25L for centration and custom shaping, a Nanotech 450UPL diamond point turning machine, and a Zygo Verifire Asphere Interferometer. The Satisloh machines can shape lenses between 2 mm (0.08") and 150 mm (5.9") in diameter. The diamond point turning machine can polish curved optics from harder materials that cannot be easily processed by the Satisloh polishers, such as lenses for the mid- to deep-IR and Thorlabs' off-axis parabolic mirrors.
