Description

TECHNICAL FIELD

[0001] The application relates to the technical field of lens quality detection, in particular to a quality detection device for high-temperature-resistant infrared laser lenses. BACKGROUND

[0002] The detection of lens quality by using infrared rays is mainly based on the characteristics of infrared rays, and the quality of the lens is evaluated by analyzing the absorption, reflection and transmission of infrared rays by the lens. The principle is that different substances have different absorption, reflection and transmission characteristics of infrared rays. Impurities, internal structural defects and unevenness in the lens will affect the propagation of infrared rays in the lens, resulting in changes in the intensity, wavelength and phase of the infrared rays. By detecting these changes, it can be determined whether the lens has quality problems.
