Optics Fabrication

HHV’s precision Optics Fabrication Lab is equipped with state-of-the-art technology and machinery to fabricate high precision optical components in the visible and infrared spectrum. We have expertise in delivering complex optical component requirements for space and defence applications using high precision machines. HHV’s Optics Fabrication Lab is equipped with high quality machines for slitting, trepanning, curve generation, grinding, polishing, centering and edging for spherical and aspherical optics.

HHV has extensive knowledge on handling materials such as Quartz, Fused Silica, Zerodur, BK7, Crown and Flint Glasses for the UV-Visible Spectrum and Silicon, Germanium, Zinc Sulphide for the Infra-Red spectrum.
