BQM-10 / NIR

The BQM-10/NIR laser beam profiler is a high precision beam profiler for use with lasers with wavelengths between 900 and 1700nm. Allied with our powerful but intuitive software package, the BQM-10/NIR makes quick and accurate characterisation of your lasers a reality.

The high quality InGaAs array gives excellent resolution, and the USB2.0 interface means that the BQM-10/NIR is small and can used with a laptop or desktop computer. The user interface is simple and intuitive but with many useful features.
