Optronic Laboratories Inc. has released the OL 756 high-accuracy UV-VIS spectral measurement system for the 200- to 800-nm range. The compact, portable, double-monochromator system features a USB interface. The company says that it is highly sensitive and produces low stray light levels, and high wavelength accuracy and precision. Operating on 12-VDC power for portable or remote measurements, the system offers narrow bandwidths and a wide dynamic range. It performs solar spectral measurements over the full range in <6.5 s.
