Test light source

The invention relates to a test light source for testing the optical performance of a camera module. The test light source comprises an array light source and a light adjuster which are arranged in parallel. The array light source comprises point light sources which are distributed in an array mode. The light adjuster is wavy relative to the surface of the array light source; light emitted by eachpoint light source in the array light source is adjusted through the corresponding wave structure in the light adjuster. The intensity of the adjusted light is in direct proportion to the optical axis included angle; when an optical performance test is carried out, a lens of the target camera module and the light adjuster are arranged in parallel. After adjustment of a light ray adjustor, light rays forming different angles with the optical axis are imaged at different positions on the surface through the imaging chip; the light ray adjustor enhances the illuminance of the light in the direction with a large included
