Although a great value for its purchase cost, I would like to see an upgrade, for a nominal increase in pricing. EX; Resolution, Clarity, slightly wider nm scale, adjustable positioning to minimize reading error, Instructional picture showing internal ray tracing.

For the price, this is a good product. The slit is a little too wide, resulting in spectral lines that are poorly defined, but that problem can be fixed without too much effort: just make the slit narrower by attaching some thin, opaque material (maybe aluminum foil) to either side of the slit. The narrower the slit, the more sharply defined the spectral lines will be. I've attached a photo (taken with my cell phone looking through this spectroscope) of the spectral emission lines from a compact fluorescent lamp (CFL).

It might not be the best or most advanced spectroscope, but it does do the job as a spectroscope.

Works very well with bright light sources. Superb learning device that is surdy enough for young hands. Wish I had one as a child!
