The WinCamD-LCM-NE takes CMOS beam profiler embodies DataRay's philosophy: providing our customers with affordable, high-quality products. Since its introduction, it has gone on to become far and away our most popular product, for good reason. Its 1" format CMOS sensor utilizes a global shutter, making it suitable for both CW and pulsed beams.
This NIR-enhanced version features improved spectral response between 400 and 1000 nm but, due to the presence of microlenses on the sensor, is unsuitable for use with UV wavelengths, and is not offered with TEL phosphor coating.
