About This Product
A spectroscope is only as useful as the light reaching its slit, and this unit provides a steady, controllable source for that job. Placed in line with the slit or collimator, it lets students set up and focus the instrument and then study dispersion through a prism or grating.
Frequently Asked Questions
How is the Light Source for Spectroscope positioned?
In line with the spectroscope slit, spectrometer collimator or optical bench set-up; the distance and alignment are then adjusted until the spectrum or image appears clear.
