Custom Anti Reflective Coating Factories & Factory Hub

For standard single-wavelength laser lines (such as 532nm or 1064nm), a narrowband V-coat routinely achieves residual reflectance R < 0.05% to 0.10%. For broadband requirements (400–700nm or 700–1100nm), multi-layer dielectric stacks hold an average reflectance R_avg < 0.4% across the entire active spectrum.

All production runs are qualified according to MIL-C-675C, MIL-PRF-13830B, and ISO 9211-4 standards. This includes snap tape adhesion testing (using high-tack cellophane tape), 24-to-48 hour humidity chamber exposure at 50°C and 95% RH, moderate-to-severe cheesecloth abrasion, and solubility immersion tests.

Yes. In addition to plano plates and windows, our facilities utilize customized planetary tooling with rotating fixtures inside physical vapor deposition (PVD) chambers for optical flow tubes, light guides, and sapphire blocks. For deep internal bores, we evaluate specialized chemical vapor or ALD configurations.

Each OEM production lot is delivered with a comprehensive Certificate of Conformance (COC), calibrated spectrophotometer transmission and reflection graphs, Zygo interferometric surface flatness maps, dimensional inspection reports, and RoHS/REACH regulatory compliance declarations.
