Hi to all. I am a new member and I hope i've posted this thread in the right section.
Well, I'm an Electrical Engineering Student.
I've got a problem.
We've been asked to answer a question about photometers or luxmeters used in the Ulbricht Integrating Sphere.
The main question is why does the luxmeter's sensor play such a big part on the luxmeter itself, and we've been asked to find different types of materials used for luxmeters sensors.
I'd really appreciate any help you can give!
Thanks! :approve:
