Description

TECHNICAL FIELD

[0001] The utility model relates to a lens transmittance measuring technology field, concretely is a non -contact lens transmittance measuring appearance. BACKGROUND

[0002] Lens transmittance refers to the total amount of light that is not reflected and absorbed by light passing through the lens. The lens clarity of high transmittance is relatively high. The transmittance of the lens is related to the refractive index of the lens, and they influence each other. The higher the refractive index, the lower the transmittance, and the two are negatively correlated. The size of the transmittance and the basic material of the lens are related (refractive index), but the most important thing is still related to the antireflection film layer plated on the surface of the lens.
