Description

Technical Field

[0001] The invention belongs to the field of product processing, and in particular relates to a lens transmittance detection device. Background Art

[0002] Lens transmittance testing is a technology used to test the light transmittance of lens materials. When manufacturing lens products, transmittance is a very important parameter that determines the performance and effect of the lens in the optical system. Lens transmittance refers to the proportion of light transmitted by the lens material, usually expressed as a percentage. Lens transmittance testing can be performed by different methods, including spectral analysis, transmittance measurement, reflectance measurement, etc. These methods can help manufacturers accurately understand the light transmittance of the lens, thereby ensuring that product quality and performance meet requirements. Lens transmittance testing is widely used in optics, electronics, communications and other fields. By testing the transmittance of the lens, manufacturers can optimize production processes, improve product quality and meet customer needs.
