See the unseen. Build the reliable.

We design and manufacture high-performance Germanium optical-grade lenses, windows and thermal camera modules for security, industrial inspection, firefighting, medical and research customers.

Fast samples, predictable lead times, and OEM scale production from India.

• Optical-grade Germanium (5N/6N) —+material traceability, low absorption, stable refractive index for MWIR/LWIR.
• Precision manufacturing —tight tolerances (diameter, thickness, parallelism), surface quality to MIL—O—13830A.
• Coating capabilities —IR AR coatings (3—5 µm, 8—12 µm), DLC for outdoor durability.
• Quality assurance —interferometry, transmission testing, lot traceability and inspection reports.
• Volume & flexibility —from prototype samples to production batches (hundreds → thousands).

• Windows & Blanks — Ø 5 mm — Ø 320 mm; wafer & blank supply.
• Thin Filter Discs — e.g., Ø13.5 × 0.5 mm (custom sizes).
• Polished Lenses — plano-convex, meniscus, aspheric & hybrid aspherics.
• Custom Lens Elements — tailored geometries for OEM modules.

• AR coatings (MWIR / LWIR), multilayer AR on Ge
• DLC protective coatings for rugged deployment
• Lens assemblies & sub-modules — assembled and tested for thermal camera OEMs

• Security & Surveillance: perimeter protection, border security, smart—city cameras.
• Industrial & Manufacturing: predictive maintenance, process monitoring.
• Fire & Rescue: smoke/obscurant penetration, search & rescue optics.
• Medical & Veterinary: non-contact thermography.
• Research & Environmental: wildlife monitoring, thermal mapping.

We supply Germanium windows and aspheric elements to OEMs building thermal camera modules used in 24/7 perimeter systems.

Typical engagement: pilot sample — optical validation → small production → scaled monthly supply with QC packs and interferometry reports.
