This semi-quantitative spectroscope is a simple and economical alternative to expensive equipment.

• Perfect for Chemistry and Physics classrooms
• Inexpensive and simple to use
• Instructions included

The Ward's® QA spectroscope has been designed to produce a bright spectrum of visible light decomposed by a diffraction grating, with a clear, easy-to-view translucent scale. Students can analyze spectra from flames and gas emission tubes, measuring wavelengths from 4000 to 7000 Å with an accuracy of +/-50 Å. The spectroscope houses a 37 mm scale, and includes instructions with suggestions for use.
