Transmission refers to the amount of light that successfully passes through the lens material without being absorbed or scattered, a critical factor in determining the performance of optical devices.
The science of refraction in high-index lens materials is intricately linked to transmission. As light encounters a high-index lens material, its path is altered due to refraction, the bending of light. However, not all of the incident light is refracted; a portion of it may be absorbed or scattered by the material, reducing the amount of light transmitted.
Understanding and optimizing transmission is paramount in designing high-index lens materials with superior optical performance. By carefully controlling the composition and structure of the material, scientists and engineers can minimize absorption and scattering losses, thereby maximizing the amount of light that passes through the lens.
