Long Wave Pass Dichroic Beamsplitters exhibit high transmission for a long wavelength band, high damage thresholds, and high reflectivity for a shorter band of wavelengths. Reflectivity bandwidth is limited by coating design, incidence angle and polarization. For high energy laser applications, specify pulse energy, pulse duration, repetition rate, and beam diameter.

Mount your mirror in the 160 mirror mount. Tilt range of +/- 5.5 degrees.
 
Tip, tilt and rotate with the 2300. This flexible stage can be mounted horizontally or vertically for a variety of applications.
 
When you need the full 45 degree aperture, use the 108 open frame mirror mount.
