StarStarStarStar

Refractive Index

StarStarStarStar

Measures the bending of light through a material - Crucial for lenses and optical fibers.

StarStarStarStar

Chromatic Dispersion

StarStarStarStar

The phenomenon where different wavelengths of light travel at different speeds through a material, causing them to separate spatially - Important for understanding image quality and color separation in lenses.

StarStarStarStar

Scattering

StarStarStarStar

The process by which particles or imperfections in a material diffuse a beam of light in many directions - Affects the clarity and color of transparent materials.

StarStarStarStar

Transmittance

StarStarStarStar

The fraction of incident light that passes through a material - Important for transparent materials and coatings.

StarStarStarStar

Luminous Transmittance

StarStarStarStar

The percentage of visible light transmitted through a material - Relevant for display technologies and lighting applications.

StarStarStarStar

Reflectance

StarStarStarStar

The ratio of the amount of light reflected by a surface to the amount of light incident on it - Significant for mirrors and reflective surfaces.

StarStarStarStar

Absorption Coefficient

StarStarStarStar

A measure of how much light is absorbed per unit distance in a material - Important for determining penetration depth and energy conversion efficiency.

StarStarStarStar

Laser Damage Threshold

StarStarStarStar

The maximum amount of laser power or energy per area that a material can withstand before sustaining physical or chemical damage - Critical for laser optics and safety.

StarStarStarStar

Birefringence

StarStarStarStar

Occurs when a material has two different refractive indices depending on the polarization and direction of light - Important in certain types of optical devices like waveplates.

StarStarStarStar

Photoelasticity

StarStarStarStar

The property of certain materials to change their refractive index under mechanical stress - Used in stress analysis and is important for safety testing and design.
