Antireflection Coating + DLC Diamond-Like Carbon Coating CSi02001
Diamond like carbon coating is a highly durable anti reflective optical coating. It has a high hardness, low friction surface, resistance to scratches and corrosion, and good transmission performance in medium to long wave infrared radiation. These characteristics make it one of the choices for thermal imaging and other defense applications. Applied in mechanical, electronic, optical, medical, aerospace and other fields. The DLC film exhibits good broadband transmittance at infrared wavelengths, but the average transmittance is slightly lower compared to the standard BBAR coating. To reduce light loss, DLC films are usually paired with traditional AR coatings. UM OPTICS can provide BBAR+DLC coating for silicon and germanium substrates.

Polarizing Beamsplitter Coatings
Optical Coatings
Rsgx
Polarizing beamsplitter coatings exploit thin film polarization effects at oblique incidence. Prism and plate types are available. Prism coatings offer broader wavelength ranges and high polarization, but are harder to manufacture in large sizes and have lower laser resistance. Plate polarizers have narrower bands but can be larger and withstand stronger lasers, so they are often used in high intensity laser systems.

Antireflection Coatings
Optical Coatings
Rsgx
Reflection at optical component surfaces causes optical energy loss. Transparent dielectric antireflection films reduce this loss. Lower reflected intensity increases transmitted intensity and improves image clarity. Common materials include magnesium fluoride, titanium oxide, lead sulfide, lead selenide, ceramic infrared antireflection coatings and vinyl silsesquioxane hybrid films. In general…

Partial Reflection Coatings
Optical Coatings
Rsgx
Reflective coatings increase optical surface reflectivity; partial reflectors divide light into reflected and transmitted portions. They are used in beamsplitters, output couplers and interferometers. Beamsplitter coatings include single wavelength partial reflectors and broadband partial reflectors.

High Reflection Coatings
Optical Coatings
Rsgx
Dielectric high reflection coatings exploit reflection and transmission at each interface of a multilayer stack. Appropriate layer thicknesses make reflected waves interfere constructively for high reflectivity. Metals generally have high extinction coefficients: light entering from air attenuates rapidly inside the metal, reducing internal transmission and increasing reflection. Higher extinction coefficients produce faster amplitude attenuation…
