Partial Reflective coatings|
| 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.
