Stray Light Tester

The Stray Light Tester is designed for evaluating the influence of stray light on the imaging quality of optical lenses and imaging systems. It is suitable for low-light objective lenses, photographic lenses, camera lenses, and various optical imaging applications.

The system mainly consists of an extended light source (integrating sphere), light absorber, lens mount, photoelectric receiving module, stabilized power supply, high-voltage power supply, guide rail, and optical platform.

With stable testing performance, good measurement repeatability, and low linear response deviation, the system is suitable for optical research, laboratory testing, and optical manufacturing applications.
