[0002] An optical lens is an optical element used to control the propagation and focusing of light, and is commonly found in various optical systems, such as cameras, telescopes, microscopes, and lasers. Optical lenses have different shapes and surface properties and are used to achieve various optical functions, such as focusing, imaging, and dispersion. Optical lenses are usually made of optical materials, such as glass, plastic, or crystal, and have precise surface shapes and optical properties. After the production of optical lenses, the transmittance needs to be measured using a transmittance meter.

At the same time, the use of fixed height and fixed position to test the optical lenses makes it difficult to test the transmittance of optical lenses at different heights and positions, resulting in poor accuracy in optical lens transmittance testing.
