Thorlabs beam viewers constitute a group of laser alignment detection products designed for viewing the beam during beam profile measurements and component alignmen. These beam viewers provides detection of all wavelengths from blue through to NIR broadband. Yellow/red emission offers clear visibility for almost every laser/laser goggle combination.
