TECHSPEC® Laser Line Mirrors offer high reflectance, surface quality, and accuracy required for demanding laser applications with Nd:YAG, Nd:YLF, and Yb:YAG lasers. With a dense reflective coating featuring a high damage threshold specific to the laser type and wavelength, these laser line mirrors are ideal for a range of applications such as those requiring durability and beam steering up to the fourth harmonic at 266nm. TECHSPEC Laser Line Mirrors are available in 0° and 45° AOI options and various harmonic designs. Dual band mirrors are available for reflecting the fundamental and frequency doubled laser lines, or for reflecting the 1064nm fundamental line and its alignment beam.

Note: Please contact us for custom wavelength and AOI options.
