Hi, I am trying to source some light measuring equipment - I can only think of a camera photometer.
I know that adjusting the temperature will change the colour of the light, projected from the prism, but can this information / data be captured and recorded?
Welcome to the forum.
I had an old type photometer. It measures light intensity.
Projected from the prism? Sounds like there is more to yourr question.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
