Testing Scope: Optical lenses, resin lenses, glass lenses, fluorite lenses, etc.
Testing Items:
Optical Properties: Covers the basic characteristics of a lens's interaction with light, serving as a fundamental indicator for evaluating lens optical performance.
Refractive Index: Reflects a lens's ability to refract light; lenses with different refractive indices are suitable for different degrees of vision correction.
Dispersion Power: Also known as the Abbe number, it measures the degree to which a lens disperses different wavelengths of light. A higher Abbe number indicates less dispersion and a clearer image.
Reflectivity: Refers to the ability of a lens surface to reflect light. Excessive reflectivity can affect the lens's light transmittance, causing glare and other problems.
Light Transmittance: Indicates the proportion of light that passes through the lens. Higher light transmittance results in a clearer lens and better visual effects.
Light Absorption: Tests a lens's ability to absorb specific wavelengths of light. For example, some special-function lenses absorb harmful light such as ultraviolet rays and blue light.
