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. |
