Spectrometers for Laser Measurement. These miniature rugged spectrometers are calibrated to measure and track laser frequency and centroid wavelength and/or total power of lasers in Watts. Currently, StellarNet offers laser measurement systems in the 200-2300nm range.
Electromagnetic energy is measured in units of wavelength and frequency. The wavelength is the distance that a wave travels in one cycle and is measured in metres. The frequency is measured by the number of cycles per second and the unit of measurement is the Hertz (Hz). One cycle per second equals one Hertz.
