Coating Laboratory:
6 coating chambers (cryo pumped and diffusion pumped)
Material deposited: Au, Al Cr, Ni, Rh, Pt, Ir, Os, MgF2, SIO2 24” apertures. Deposition sources-
Diamond Turning Laboratory:
5 single point diamond turning lathes. 36” plano apertures, curves, spheres. Materials, Al, Cu, ZnSe, Ge.
Ruling Laboratory:
6 Ruling engines. Each engine with its own dedicated temperature controlled room. Ruling engines are geared and sequenced for certain designs of diffraction gratings. Wavelength coverage and groove densities vary; Far IR to soft Xray
Line spacings:
7.2 millimeter per line/groove up to 7,200 lines per millimeter.
Blaze angles: 0.1º-
Substrate Dimensions:
Up to 1,000 x 1,000mm (40x40”)
Gratings:
- Type 1 Gratings, VLS gratings, Reflection and Transmission.
- IR gratings/ High Laser Damage threshold gratings-
on metal substrates - Invar, Cu etc. - Curved gratings for Hyperspectral applications -
Offner/ Dyson gratings. IR- UV - Fastest radius ~23mm convex / concave to Plano. Spheres and toroids - High line density gratings for UV-
Xray. Typically, 3,600 - 4,800 up to 7,200 l/mm
Original grating / Master grating:
Gratings ruled into a deposited metal film onto/ into a substrate of certain material.
Glass, ZnSe, CaF2, Al, Cu, Invar, Stainless Steels. Once a Master grating is
completed, we can make hundreds of replica copies from that Master.
Replicated Gratings:
The grating is replicated from a Master/ Original grating into an !epoxy film that is
over coated with a metallic coating for reflection or for transmission.
Testing Areas:
Multiple Lasers, HeNe, HeCd, Air tables.
Microscopes, Nomarski, Interference Microscopes, AFM
12” Zygo, Wyko, AFM profilers, Spectrometers, Angstrometers.
