Abstract: A multi-channel array spectrometer combines a spectral measurement system and a reference detector which measures photometric or radiometric qualities. High accuracy photometric or radiometric measurement of a wide dynamic range can be achieved by correcting measurement results of the reference detector with a spectral correction factor. The multi-channel array spectrometer comprises a bandpass filter wheel holding a set of bandpass filters and an open hole. The wheel is placed between an entrance slit and gratings. A test light beam passes through a turret of the bandpass filters. The test light beam can be precisely measured band by band. The spectrometer can also quickly and accurately measure a plurality of test light sources having similar spectral characteristics by using the stray light correction factor.

Abstract: A goniophotometer includes two independent towers: a main support tower and an upright mirror tower. A swing arm is connected to the main support tower and can be rotated around a main horizontal axis. An elliptic flat rotation mirror, a first detector and a second detector are fixed to the swing arm. A test light source that is also connected to the main support tower can be rotated around a vertical axis. An upright round mirror is connected to the upright mirror tower. A far-field measurement can be achieved when a light beam from the test light source travels into the rotation mirror then is reflected to the upright mirror, and then is reflected by the upright mirror to the first detector. A near field measurement is achieved when the second detector receives a test light beam directly form the test light source.
