Optics Rapid Prototyping (ORP) Capabilities

Silicon Micro Lens Array

We’ve produced a micro lens array using diamond turning (Nanotech 250UPL with 3 axis). The process involved slow speed servo (C-Axis) with a cycle time of 50Hrs (including roughing, semi-finish, and finish). Targeted results are Rq-10nm and surface quality 60-40, we’ve achieved results of Rq-6 to 9nm and surface quality 60-40.

Bi-Conic Copper Mirror

We use 3 axis diamond turning machine to make a bi-conic copper mirror using slow
speed servo process. Targeted roughness Rq<10nm and form error<0.6 microns, we’ve achieved results of Rq 3nm and 4nm, and PT=0.3 microns and 0.6 microns.

Off Axis Parabolic Mirror

These off axis parabolic mirrors, copper (F250 and F100) and aluminum (F100 and F12.5), are machined using 3 axis diamond turning machine. Targeted roughness
Rq<10nm and form error<0.6 microns, we’ve achieved results of Rq= 10 nm and PT=0.25 microns.
