Hi All.
I inherited a small spectroscope - it was destined for a skip as no one had used it in years, there was no way I was seeing it going to land fill...
P1150252 by Mark Townley, on Flickr
It is in excellent condition, just missing either a prism or a grating - which would be best for me to get?
I plan to use this when I do outreach as a 'curiosity' - people like to look through things. What can I expect from it? Are there any tricks I can do to make it more appealing to the masses? Any web links to anything exciting I can do with it on outreach duty?
Mark

Re: Inherited a Spectroscope - help please!
From picture holder looks like it was designed for a grating
reflective grating look like a small mirror about 6mm thick , 25-50mm square
but of course i may be wrong

These student spectroscopes provide a great introduction to spectroscopy.
I have almost an identical unit.
They use either a 25mm 60 degree prism (Thorlabs) or usually a 600l/mm transmission grating. You can use any suitable transmission grating (Paton Hawksley)
You can start by looking at the spectra from various lamps/ filters etc. Use a small mirror to direct sunlight into the slit and view the Fraunhofer lines.
It's too heavy and cumbersome for telescope spectroscopy.
I removed the eyepiece and fitted a Baader micro focuser to allow me to use a webcam.
Enjoy!!!

Mark,
Have a look on Amazon or Alibris for a copy of Baker's "The Spectroscope"
It complements the student spectroscope nicely.

A very nice summer project, that was a lucky find

Lovely bit of kit Mark - used to enjoy playing with those when I taught the odd physics lesson. Yours has the same clip for a grating that I remember - we used relatively cheap 600 line material mounted in a 35mm slide frame; remember what 35mm slide film was/is returned in? You can have lots of fun looking at different light sources and should be able to resolve the sodium doublet fairly well.
Have fun!
Have fun!

diffraction grating and 60 degree prism acquired this morning before they too were skip bound
Thanks all
