What's this price of equipment?

Mother has just come home with some kind of science equipment, we tbink it's something for measuring light reftaction of some kind.

Anyone have any other ideas?





Thanks science people of PH

Griffin & George - well known makers of scientific and teaching equipment.

I suspect that the thing on top is a lamp? With provision for focussing lenses, colour filters and a slot to cast a beam of light across the disk, where the clips would hold ?prisms? ?other lenses? and the protractor disc demonstrate the angle through which the light has, as you say, been refracted. So a demonstration refractometer, for school or university use.

Thanks for the explanation John. Glad we were in the right area then.

This might help explain how it works:-

I thought it might be a very precisely calibrated "Wheel of Fortune".

Don4l, that is brilliant. Many thanks for the link for that. Once we get the lamp wired properly will have to fire it up.

Thanks again.

Well done, Don! Wish I could have found that manual!
Do you have the various mirrors, lens and prisms, eggchaser?

The link's not working for me, but I'd say it's a piece of HG Wells' Time Machine. Don't spin it too fast...
