🔬 EISCO Resolution Quantitative Spectroscope 400 700: Enhancing Spectral Analysis Accuracy Review

At this price point it's not fair to give less than 5 stars. The spectroscope scatters light and the instructions in the Experiment Guide are helpful and good. The small picture of the spectra in the description is probably the picture taken when the spectroscope is pointed at the LED display. I wear trifocal lenses and the spectrum becomes clear when I move a little away from the viewing port. This spectroscope works. Finding different light source sources is a difficult task. At this price…

I got this for my son's science project to see how light color affects plant growth. I can't speak to the quantitative accuracy of this spectroscope, but it's great for a fourth grade science fair project. This helps him understand that the light he sees can be made up of many different colors of light, depending on the source. He thinks it's really cool and has used it to test different lightbulbs around the house. The build quality is satisfactory - it's plastic. But for the price it's ok…

I wouldn't even use this for a classroom demonstration. There are many visible images of the spectrum and it is not immediately clear which one to use. (I suspect the scale is upside down.) I couldn't always find one that lined up with the scale. The slit is too wide to show clear lines. Disappointing and disappointing. I've had better luck with one I made myself by cutting out a grid out of toy rainbow goggles and a slit of cardboard and black tape, all attached to a paper towel tube. Of…
