Abstract

The water ball lens is a simple, thick convex lens made of glass balls filled with high purity water. In this paper, the imaging quality of water ball lens is quantitatively analyzed by ZEMAX optical design software. The analysis results show that the water ball lens has the characteristics of large field of view and good imaging quality, so it can meet the needs of astronomical observation in large field of view.
