Product Code: ATR20202
application
ATR20532 633nm narrow line laser is characteristic by its high reliability and ultra-narrow line-width. ATR20532 operates with a single 5V power supply and can output 300 mW laser power. When ATR20532 is used in Raman spectrometer, it will help to obtain high spectral stability and high resolution. It can be controlled through the TTL interface by the offered pin-out definition and the communication protocol. The output laser power can be changed continuously by changing the LD working current with the commands.
