Abstract: An optical sensing system and a color analyzer with the same are provided to improve accuracy and redundancy due to directionality of a liquid crystal display panel by using a telecentric optical system. An optical sensing system includes a condensing device(420), an optical uniformization device(430), an optical receiver(440), and a signal processing body. The condensing device condenses only a ray having a radial angle less than a predetermined value among rays irradiated from a measuring target area to one rear condensing surface. The optical uniformization device diffuses the ray condensed on the condensing surface. The optical receiver receives a part of the rays transmitted from the optical uniformization device to a rear direction and determines a received optical spectrum range. The signal processing body calculates optical and color characteristics corresponding to an optical signal received by the optical receiver.
