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.
You'll use a laser pointer and a hollow glass prism (which you'll be shown how to make). Diagram of setup for measuring the index of refraction of a liquid using a laser pointer and a hollow triangular prism (not to scale).iagram of setup for measuring the index of refraction of a liquid using a laser pointer and a hollow triangular prism (not to scale; based on the diagram in Nierer, 2002). 1  The laser pointer should be set up so that its beam (dotted red line in Figure 5) is perpendicular to a nearby wall.
