What is a Gradient Index Lens?
A gradient index lens is an optical lens in which the refractive index is not uniform but changes gradually across the lens material. This design enables unique light propagation properties, including improved focusing and reduced distortion compared to traditional spherical lenses.
Key benefits of GRIN lenses include:
- Compact size with high optical quality
- Superior focusing ability with reduced spherical aberrations
- Easy integration into compact imaging and optical communication systems
- Enhanced transmission efficiency in fiber optics and laser systems
These properties make them indispensable in modern optical and photonic applications.
