The laboratory consists of various machines for curve generation, centering, edging, trepanning, slitting, polishing and grinding for spherical optics and prisms. Substrates up to 200mm diameter can be processed. It is proposed to add single point diamond turning, shortly to expand its capabilities to aspheric fabrication and address diverse applications.

HHV has a comprehensive understanding of various MIL specs, ISO specifications and customer issued quality documents. The test lab houses sophisticated instruments to measure surface roughness, surface figure using Zygo interferometer, angles and parallelism by Nikon Autocollimator. Experienced Optical Engineering team can identify the most challenging features and devise unique manufacturing solutions.

HHV specializes in supplying Thin film coatings for the UV, Visible and Infra red spectral regions. Vacuum coating chambers are housed in clean rooms and can accommodate different substrate sizes and shapes. State of the art technology is used to produce optical coatings with excellent spectral performance, Laser damage threshold and environmental durability.

Advanced thin film design software and theoretical evaluation techniques are used to develop optimal coatings. Coating chamber parameters are rigorously controlled to ensure process repeatability. HHV has a unique advantage of building its own vacuum coating chambers in house with the latest features incorporating automatic process control.
