Foctek can make most optical coatings on all kinds of glass, infrared crystal and metal substrate, but also can develop special films according to customers' needs.
Combined with a variety of coating techniques (evaporation, sputtering, RF ion source, oil-free vacuum system and large substrate coating, etc.) and all kinds of high precision optical coating equipment (e.g., lai treasure, chi and light design and production of coating equipment), make the company accurate unique precision plating system and film thickness control technology.
Foctek produces a wide range of coatings, from simple single-layer AR coatings using MgF2 and mirror coatings to complex multi-layer dielectric coatings.Various anti-reflective (AR coating), high-reflective (HR coating) and partial reflective (PR coating) coatings are available upon request.Typical dielectric coatings are BBAR, v - type coatings and double - wavelength coatings.
Foctek used perkin-elmer 950(UV/VIS/) to measure the spectral curve of the coating
