37 years of depositing thin films on precision optics. Optical coatings on glass, plastic, metal and fiber optics. From the UV to the NIR. Known for durable metallic coatings and handling of smaller optics (some as small as 2mm), GCL’s coatings have been tested (via 3rd party testing) to meet or exceed most MIL spec requirements.

Capabilities include but not limited to mirror coatings (enhanced & protected silver, gold and aluminum); conductive ITO; High Reflectors (laser mirrors); ND Filters; Beamsplitters (metallic & dielectric); Broadband (anti-reflective); MgF2, V-coats, polarizers, narrow band and dichroic filters.

From R&D to high volume production.
