产品概述
ATR20532-300mW 532nm 窄线宽拉曼激光器
GENERAL DESCRIPTION
ATR20532 532nm narrow linelaser is characteristic by its high reliability and ultra-narrow line-width. ATR20532operates with a single 5V power supply and can output 300 mW laser power. When ATR20532is used in Raman spectrometer, it will help to obtain high spectral stabilityand high resolution. It can be controlled through the TTL interface by theoffered pin-out definition and the communication protocol. The output laserpower can be changed continuously by changing the LD working current with thecommands.
