We provide a wide variety of coatings from simple single layer antireflection coatings using MGF2 and mirror coatings to complex multilayer dielectric stacks. Typical types of dielectric coatings are BBAR, V-coatings, Dual wavelength AR coatings, PBS, Broadband Partial Reflective Coatings.
Coating type Properties and Application
Single layer MGF2 The most popular antireflection coating for visible. They are insensitive to change in incidence angles.
Multilayer "v" Used to provide low reflectance with in a narrow durable wavelength broadband for most laser application. Minimum reflection can be less than 0.1%.
Broadband Multilayer These coating have excellent performance over broad spectral range broadband. Coating performance is sensitive to angle of incidence.
Dual Wavelength Band Offer very low reflectance at two widely spaced wavelengths.
2 Partial Reflection
Narrow Band Provide 50% reflection and transmission at an angle of 45 incidence for a single wavelength. Perfect for beamsplitters application. Transmission/reflection(T/R) ratio of 20/80, or others for Beamsplitter is a available upon request.
Broadband Over a wide bandwidth provides 50% reflection and transmission. We can also provide coatings with different R/T ratios at and specific angle of incident.
Laser line polarization beamsplitter High reflection for s-polarized and antireflection for p-polarized for laser application
Broadband polarization beamsplitter Wide wavelength bandwidth provide high reflection to s-polarized and antireflection to p-polarized.
5 High Reflection
Dielectric High Reflective coatings Provide high reflectance over a broad bandwidth, and is ideal for a tunable laser or in white light applications.
Metallic High Reflective Coatings They are insensitivity to angle of incident light and polarization.
