Five Products
NB1-K13 (Dual Wavelength): 532 nm and 1064 nm
NB1-K14 (Fundamental Harmonic): 1047 - 1064 nm
NB1-K12 (2nd Harmonic): 524 - 532 nm
NB1-K08 (3rd Harmonic): 349 - 355 nm

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°.
