Precision Optical Manufacturing Facilities for Aerospace, Defence & Space
CNC Optical Grinding & Polishing Facility India
Our CNC optical grinding and polishing facility in India operates high-precision multi-axis machines producing spherical, aspherical, and freeform optical surfaces. Serving aerospace, defence, and semiconductor industries, we achieve surface form errors of λ/20 and surface roughness below 1 Å RMS — backed by full interferometric verification for every component.
Vacuum Thin Film Coating Services India
Among the few providers of LIDT-rated vacuum thin film coating services in India — we deposit AR, HR, beamsplitter, bandpass, and notch coatings optimised for UV, visible, and IR spectral ranges. Coating solutions meet MIL-SPEC and laser-damage threshold standards for high-power defence and industrial laser optics programmes.
Optical Metrology & Interferometry Lab India
All optical components are verified in our optical metrology lab India using Fizeau interferometers and white-light optical profilers. Wavefront error, surface form, power, and irregularity measurements are fully traceable to national standards — supporting ISO 9001:2015 & AS9100D certified quality systems for defence prime contractors.
Optical Centering & Edging Machine Facility Tamil Nadu
Located near Chennai, our optical centering and edging machine facility Tamil Nadu provides tight-tolerance centration for single and multi-element lenses, prisms, and windows. Achieving wedge errors below 10 arcseconds, we supply centering and edging services for surveillance, EO/IR, and space payload optical assemblies.
Trioptics Opticentric & Prism Master Testing India
Among the few facilities in India operating Trioptics Opticentric and Prism Master instruments — we deliver automated centration error and angular deviation measurement for lenses, prisms, and complex optical subassemblies. Full material traceability, AS9100D documentation, and environmental screening ensure readiness for defence and space integration.
