Light Measuring System

The CW-330 offers a simple and highly accurate way of detecting and measuring the RGB colours and brightness of light sources.

The connection is made via fibre optic cable. The CW-330 supports a sampling rate of up to 200 Hz and a resolution of up to 14 bits. Output is convenient via Ethernet and the associated configuration software is web-based. The module achieves high scaling thanks to an adjustable amplification factor between 1 and 4096.

The module is available in a robust 19-inch housing for use on test benches. One area of application for the CW-330 is automated measurement for function validation of light sources in the automotive sector. The CW-330 is the ideal complement to our CW-300 series in the test bench sector.
