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…

Technical Specifications 

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

• high quality optical components ensure that absorption bands show up clearly – even weak bands that are sometimes difficult to detect.

• The unit is of fixed construction – no need for adjustment.

• Robust assembly to withstand years of student handling.

• Convenient size, 115mm x 25mm.
