To assess the influences of non-imaging light radiated or reflected by sun, cloud and earth surface on space optical systems, a set of stray light test equipment with a 1-meter aperture is established by simulating the space environment on the ground. According to the development experience of advanced stray light test equipment of foreign countries, a double cylindrical chamber is used in the equipment. So, it can reduce the light pollution such as the reflection, scattering and diffraction in the test environment and make the test accuracy lg(measurement value/true value) of Point Source Transmission (PST) to be less than ±0.5. The operation principle, components and function of the equipment are presented. The equipment is used to test the PST curves in the visible spectral band both in the west-east direction and in the north-south direction. The stray light suppression of the camera can be up to 10-6 order of magnitude. The measured curve is in good accordance with the theoretical simulation curve. This shows that the stray light test equipment has high accuracy and reliability and can meet the stray light test requirements of space optical systems.
