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.
