NITROLUX™: Trace Ammonia Analyzer For Industrial Applications

Turn-Key, Multiple Wavelength SWIR, MWIR and LWIR Laser System

Laser Head
Laser Controller

Model MULTILUX™-20-40-46-CW-SYST is a high power multiple wavelength laser system that provide multiwatt of continuous wave room temperature power output at one short wavelength infrared (SWIR) and two midwave infrared (MWIR) wavelengths. The three laser outputs are collinear and collimated and each has excellent beam quality needed for a variety of defense and homeland security applications.

The MULTILUX™-20-40-46-CW, can be configured to provide > 2 W of continuous wave, room temperature (CW/RT) power at ~4.6 µm, > 1.5 W of CW/RT power at ~4.0 µm and > 3 W of CW/RT power at ~2.1 µm. The collinearity between the combined laser outputs at the three wavelengths is better than 1 milliradian, which coupled with the excellent beam quality of all three lasers allows projection over long distances. Power output at each one of the laser wavelengths can be individually controlled and can be modulated with arbitrary pulse sequences. Other combinations of SWIR, MWIR and long wave infrared (LWIR) wavelengths are available.
