15 Apr 2019 Partial Reflection(PR)coating 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 the 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 arround 5%.
There is a kind of super wideband PR coatings that can split beam in awide light region from UV,visible to infrared .This coating is widely used in optical components. |
