Description

TECHNICAL FIELD

[0001] The utility model belongs to optical lens testing tool technical field, concretely relates to an optical lens flare testing device. BACKGROUND

[0002] In optical photography and imaging technology, flare is a complex and important phenomenon, especially when shooting light sources or strong light objects. Flare often manifests as a halo at the edge, a shadow, or a bright spot radiating outward, which has a significant impact on the final imaging effect of the camera.

[0003] The generation of flare is mainly due to the reflection and scattering of light by optical elements inside the lens. When light from a strong light source (such as the sun or artificial light) directly hits the camera lens, these light rays reflect and bounce off different elements, apertures, and even sensors inside the lens. This reflection and scattering causes the light path to deviate from the original designed light path, resulting in unwanted flare in the image.
