Partial Reflection (PR) coatings provide attenuation functions and are generally applied to output mirrors of laser cavity. Our company can design the PR coating with reflectance from 10% to 99.7% to achieve the desired performance.

Glas Opticslens can provide a wide variety of optical coatings for simple layer AR coatings using MgF2 and mirror coatings to complex multilayer dielectric stacks.  

Main coatings include: Anti-Reflection Coating (AR), High Reflective Metal Coatings, Dielectric HR Coating (HR), Partial Reflective Coatings(PR), Beam Splitter coatings ,etc .

Partial Reflection (PR) coatings provide attenuation functions and are generally applied to output mirrors of laser cavity. Our company can design the PR coating with reflectance from 10% to 99.7% to achieve the desired performance.  

Wideband PR coatings are typically used at 45 degrees angle to the beam splitting of wideband light, such as 50/50,40/60,30/70 with error at around 5%.

There is a kind of super wideband PR coatings that can split beam in a wide light region from UV, visible to infrared. This coating is widely used in optical components.
