Metrologic Hard-Seal Helium-Neon Laser ML-868

　　The ML 800 series of lasers is a tried and true laser design originally manufactured by Metrologic. Industrial Fiber Optics is proud to continue producing this outstanding line of lasers, incorporating our own improvements. They are based on a proven classic design using a high-quality laser tube, integrated power supply and sturdy metal enclosure. Their superior performance makes them an excellent choice for industrial or educational applications.

　　The ML 868 laser has the Class II power classification widely used in educational institutions. It shares the features of the ML 800 series and adds the capability for amplitude modulation of the laser beam intensity at audio frequencies. The optical output features a small beam size with low divergence. The ML 868 is one of the best and most versatile lasers in the product line.
