...quality and precision





























Thin film coating is a vacuum deposition procedure used to enhance the transmissive properties of an optical surface. The most common types of dielectric coatings are anti-reflection and high reflection coatings, but beam-splitter, band pass filter, edge filter, and polarizing coatings are also available. Because thin film coatings are more durable than optical glass, coatings also help protect an optic surface from scratches and the environment.

The sample coating curves listed below include MgF2, single and dual wavelength anti-reflection, broadband anti-reflection, and both metal and single wavelength dielectric mirror coatings. These coatings can be modified for specific wavelengths, angles, and polarizations to meet project requirements.

Antares Optics performs test runs of all coatings before beginning production to ensure a good design. We use a Spectrophotometer to check the performance of the coating upon completion. Adhesion, abrasion, and humidity tests are available to verify coating durability in accordance with sections of MIL-C-675C, MIL-C-48497A, and MIL-C-13508C specifications.
