Abstract:
An apparatus for measuring light properties includes a housing defining a light input port; as well as a first light detector; a second light detector; and a coupling element. The first light detector is a single channel light detector or a multiple channel light detector. The second light detector is a multiple channel light detector. The coupling element is configured and arranged to selectively couple light incident from the light input port to one of the first light detector and the second light detector. As an alternative, a beam splitting element can be used instead of the coupling element. The beam splitting element receives light from the light input port and then splits the light and delivers a portion of the light to the first light detector and a portion of the light to the second light detector.
