Transmission eccentricity and reflection eccentricity of optical lens

The main difference between transmission eccentricity and reflection eccentricity of optical lenses is that the definition and principle are different:

- Different definitions:

- Through eccentricity: when the light from one medium into another medium, due to the different refractive index of the medium, resulting in the incident light and refracted light deviate from the original direction, and the deviation Angle is different, the light is refracted in the process, and the deviation occurs. To see through the eccentricity, we can use a refractor, which refracts the light so that we can observe the deviation of the light.

- Reflection eccentricity: Reflection eccentricity is when light from one medium into another medium, the Angle of the incident light and the reflected light are different. To observe the eccentricity of the reflection, we need to use a reflector, which reflects the light so that we can observe the deviation of the reflected light.

- Different principles:

 - Transmission eccentricity: measured by light refraction.

- Reflection eccentricity: measured by light reflection.
