Mini High-Resolution Laser Spectrum Analyzer

MICRO Spectra is the only mini laser spectrum analyzer giving you access to high spectral resolution. You can perform measurements on a simultaneous bandwidth of a few nanometers within 630-1100 nm.
Thanks to SWIFTSTM Technology, forget about recalibration.
MICRO Spectra is a very easy and affordable tool to control your narrow-linewidth laser sources.
