Re: Glass....

Hi All,
The prism that comes with the Student Spectrometer SP-9268 is a
dense flint glass prism. It is glass type:
"Pilkington" DF620364
or
"Schott" F2620364
Indicating that it has an index of refraction of 1.62 and an Abby #
of 36.4.
I hope this helps.
Yours,
Robert

What is the difference between crown glass and flint glass?

I have a related question. Which glass are the prisms we buy from Edmund,
Cenco, Pasco, Fisher, etc.? The catalogs don't say, nor does any
documentation I can find. I'm looking for the index of refraction of the
prisms in a spectroscope experiment.

Don't you measure the index in the experiment?
What kind of experiment is it?

Leigh
