OSK21NO103AB Infrared He-Ne laser

Infrared He-Ne laser
Application
        Infrared light source for measurements, light source for gas absorption meter, development of infrared photoelement, performance test light source
Features
    1. It realizes the stabilized feature as the He-Ne laser light source in infrared area
    2. 3 types of lasers:1.15μm, 1.52μm, 3.39μm
    3. 1.52μm laser is for optical communication
    4. 3.39μm is absorbed by methan or ethan, so it is very suitable for the evaluation of combustion characteristics of engine
Effect
        Long life span, high quality
