    Got the spectrometer yesterday. It’s an excellent little device. The software does as it should once setup. This is truly bringing tech to the common experimenter. I’ve been fooling with it since it got here. I plan to use it to checkout coatings on laser optics. I may buy the light source next. A true value, well built.
