Question spectrometer

5 months 1 week ago #41430 by Andreas Tober
Hi, I am trying to find some information on a piece of equipment which I have never used in a hurry.
We had this in the cupboard for years, it looks like this one www.eiscolabs.com/products/ph0621
I don't have the holder for the prism, but a flint prism we have looks suitable. not sure what the holder seen in the bottom right of the eisco photo does. I guess grating but could not get anything with a grating does it need a reflection grating?

sorry but year 12 are doing projects and its fairly hectic

they are surprisingly easy to setup, once you work out what all the knobs are and have done it once.
we have about 5 different versions here. That style (ours is blue I think branded Philip Harris, older than my time here) is our least favourite of them all.

Ours has the same eyepiece size as our microscopes - so one of our old goose-neck video camera adapters fits - which means it's useful for demonstration with a projected eyepiece display.

Thank you, this will certainly help me to make use of this and I like the idea of using a camera to let a whole class see.
For now the student who wanted to use it, is doing a different project and I have to leave this until the summer break.

We use them with bright LEDs as a light source. There is a Kerboodle practical in the astro section about stars and we use the spectrometer to work out the wavelength of the LED emission.
