This laser detector calibration laser module  adopts unique laser peak power attenuation technology, which can accurately attenuate the output laser power and achieve continuous adjustment of the full power range; specifications such as laser pulse width and repetition frequency are adjusted in real time. The output spot uses a homogenizing optical system to achieve flat-top light output, and the spot uniformity is better than 10%. This type of calibration light source is available in 1064nm and 1550nm bands.
