Diffration Grating Wanted!

Hi Group

Doen anyone know a good source of "not so expensive" diffration gradings
(600 to 1200 g/mm)? I would like to experiment with spectroscopy and maybe
spectrohelioscopy.

Thanks

Try Edmond Scientific in N.J.?

I bought mine ( a 50*50mm , 600 g/mm) from Richardson Grating Labs USA (now
Spectra-Physics), and constructed a very servicable spectrometer using it. A
sine arm controls the inclination of the Littrow-mounted grating, using a
Mitutoyo digital micrometer.
Digital readout is closely linear to wavelength.

Do a search on eBay for diffraction gratings. Check the blaze wavelength as
many of them are IR or UV gratings. Sometimes precision B&L gratings come
up. You must be patient! I have only seen reflection gratings so far.
Thin film type holographic gratings 'transmission' type are available from
Learning Technologies Inc. Do a search with google for them.
