ABSTRACT:
A light meter for measuring photometric quantities includes a telephotometer having a photo detector to receive light energy entering the telephotometer. A light metering valve, for the purpose of providing a variable field of view, is located in the body of the telephotometer generally at the focal plane of the objective lens of the telephotometer. A controller, which includes a digital processor in communication with the photo detector will process information from the photo detector and from a range finder included in the system to output light intensity of a target light source.
