Optical filters are precision optical components designed to select specific wavelength bands by light interference, diffraction, absorption and reflection.
We adopt advanced ion beam sputtering (IBS) interference coating technology instead of traditional dyed colored glass absorption coating. Custom-designed coating layers and substrates deliver ideal transmission curves and stable optical performance.
All hard-coated filters comply with MIL-C-48497A standards on adhesion, abrasion resistance, temperature and humidity tolerance, perfectly suited for precision optical systems and OEM integration.
Core Coating Technology: IBS Ion Beam Sputtering
IBS technology bombards target materials with high-energy ion beams to deposit uniform multi-layer thin films on glass substrates.
Precise control of ion energy, incident angle and target materials enables customized bandwidth and wavelength design.
-Ultra-dense hard coating, low wavelength shift, wipeable surface.
-Excellent thermal & corrosion resistance, dual-side coatin.
-Consistent optical performance comparable to imported filters, cost-effective replacement solution.
