Spectrum Detector's new line of USB-powered digital joulemeter instruments feature single- and two-channel LabView applications software for laser energy measurements and experiments.

These products include models based on pyroelectric detctors for sources in the 0.1-to 100-um region and extremely sensitive models including silicon and germanium detectors for measurements to the femtojoule range from 0.2 to 1.8 um.

A modular design allows the user to interchange the detector module with the digital backend and optical front end. All joulemeter products feature NIST-traceable calibration.
