Our Master Opticians have an in depth understanding with regards to all optical substrates including even challenging Exotic Crystals. We typically achieve 3Å surface micro roughness and parallelism to within 1 arc sec over a 3" diameter. Substrate size
We are the premier manufacturer of resistance heated evaporation sources and materials for vacuum evaporation (vacuum metallizing). These sources include evaporation filaments and boats, ion beam and electron beam filaments.
