Mesa Photonics compact, pre-aligned Herriott cell is easy-to-use and can be set up in just a few minutes. It gives you a 6-m-long optical path length in a structure that is only 30 cm long and weighs just 400 g including fiber collimator and detector. Simply attach the fiber from your laser to the collimator and a coaxial cable to the detector, and you are ready to run. No additional optics or alignment are needed. The cell is ideal for outdoor open path measurements including deployment on board UAV’s.
