Designed for 0° and 45° Angle of Incidence (AOI)
High Reflectivity for both S- and P-Polarized Light
The NB1-K series of Nd:YAG laser mirrors have a dielectric coating that was designed for use at 0° and at 45°, which eliminates the need to switch mirrors when altering the layout of the optical setup.
Thorlabs offers other laser line mirrors, including Ø1/2" Nd:YAG mirrors designed for a AOI of 0°.
