This instrument is an enhanced version of our popular Intermediate Spectrometer.  Its larger 30mm diameter optics give brighter line images and make precise measurements easier.  The optical focusing system has also been refined and the instrument retains the same premium features as the…

The set contains 6 glass lenses: one each of double convex, plano-convex, concavo-convex, double concave, plano-concave, and convexo-concave. Includes a reusable cardboard storage box.

During most of their life, stars are mostly composed of hydrogen and generate energy by converting it to helium. Although other elements are present to give individual stars their “fingerprint” the lines of hydrogen and helium are visible in stellar spectra, as in this tube. The…

An excellent hand held spectroscope for viewing the spectra of many different light sources. Durable construction with compound prisms and converging lenses made of high quality optical glass.
