The Kruss Spectroscope facilitates precise readings from 400 to 700nm.
This handheld Kruss spectroscope features a precision, variable slit for crisp, clear spectra and a built-in wavelength scale for readings from 400 to 700nm. This kit includes a stand, spectroscope holder, and conoscope and polarizing filters, so it can be used as a polariscope. Works better with Kruss Light Source, GMKR20
(double light pipe - one arm for spectrocscope and one arm for the polariscope). Needs GMKR1401
to work with GMKR20.
