This visual handheld spectroscope is a 115mm long tube with a very precise entrance slit which provides a very good resolution for such product. It is very easy to use on any light source: the sky (solar spectrum with Fraunhofer absorption lines), flame test in chemical analysis, absorption spectra through liquids, bright lines from discharge tube or any desk/street lamp...

This handheld spectroscope is ideal to use in classroom, during scientifical public outreach or simply for you to look at street lamp differently!


Features:
* Large diameter eyepiece aperture facilitates comfortable viewing of the SINGLE, LARGE and BRIGHT SPECTRUM which is CENTRALLY PLACED in the field of view.

* The unit is of fixed construction - no need for adjustment.
* Robust assembly to withstand years of student handling.
* Convenient size, 115mm x 25mm.
