Abstract We describe the design and construction of a new rapid 3-channel CCD photometer, dedicated to simultaneous multicolor photometric observations of rapidly variable objects. This photometer is equipped on the 1-meter telescope at the Xinglong Observatory. It allows simultaneous imaging within fields of view of 18.8′ × 18.8′, 18.2′ × 17.6′ and 9.2′ × 9.2′ in the Sloan Digital Sky Survey’s g′, r′ and i′ bands, respectively. The results of its calibration and performance are reported.
