Abstract

Water ball lens refer to a simple thick convex lens made of glass spherical shell filled with highly pure water. Besides, the image of water ball lens is not a plane, but half of the spherical image with the photo-center as the center and effective focal length as the radius. Water ball lens have good symmetry of the ball, and the detection of each direction is consistent. The imaging performance of water ball lens is the focus of this paper. In this paper, through the test of the water ball lens with a diameter of 35cm, the transmittance of the water ball lens under the measurement conditions is given.
