Abstract
An image-splitting color meter. The image-splitting color meter is added at an entrance pupil of a light coming from an observing object to obtain a high uniformity and a high efficiency. The image-splitting device can split the entrance pupil into several partitions for light splitting and color filtering. The split light beams are then converged and focused onto a photodetective plane.
