AR/IR & DLC Coatings
General Optics provides AR coatings for SWIR/MWIR/LWIR optics and DLC coatings for abrasion resistance.
Coating design, deposition, and verification are managed in-house for stable production quality.
Coating Coverage / Options
- AR: SWIR / MWIR 3–5 µm / LWIR 8–12 µm (up to 3–14 µm by request)
- DLC: wear/abrasion-resistant top layer (optional, per application)
