Homework Help: Photometers & Sensors

  1. Apr 2, 2006 #1
    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:
