Paper Abstract

The wide field survey telescope (WFST for short) is a new generation survey telescope located in Lenghuzhen, Qinghai Province in China, and has outstanding performance in sky survey. However, the feature demands a rigid flatness 20μm PV of the prime focus plane of the prime focus camera. The CCD290-99 flatness 15μm PV and -100°C working condition pose challenges to the CCD splicing. In order to verify the CCD mosaicing technology for WFST’s prime focus camera before the sensor arriving, we use the CCD 303-88 in our lab to set up the verification platform. In this article, we mainly introduce the recent research status of the platform.
