A-Star Photonics has 2 coating machines, capable of producing various coatings like AR, HR, PR, PBS, Metal (Al, Ag, Au), and MgF2 protective ones. It employs diverse optical coating techniques such as thermal evaporation, plasma-assisted CVD, and sputtering. Its coating experts solve new application issues. For detailed specs, see product links.
AR Coating
Anti-Reflection Coating is a type of coating which can greatly reduce reflection when a light through the surface of optical devices. It often called the AR-Coating.
HR Coating
HR Coating / High-Reflection (HR) Coating work the opposite way to anti-reflection coating. Anti-reflection can greatly reduce reflection when a light through the surface of optical devices,
PR Coating
Partial-reflection coating (PR Coating) is always used in beamsplitters application. There are two kinds of partial-reflection coating: Single Wavelength Partial-Reflection Coating and Broadband Wavelength Partial-Reflection Coating.
PBS Coating
PSB Coating can generate special high reflectance to S-polarization and high anti-reflection to P-polarization for laser application. It can achieve nearly 100% reflectance to S-polarization ...
Filter Coating
Other Coatings, A-Star Photonics can also supply many other custom-made coatings upon customers’ request, like Metal Coating, AL Coating, AG Coating, Au Coating, MgF2 P-coating etc.
