Slow Axis Collimation (SAC) Cylindrical Lens Array is an optical component that arranges multiple cylindrical lens units on a single substrate. Coligh is the manufacturer of SAC lens array -
Diffractive microlenses are optical devices that use the Fourier optical principle to regulate the incident light. The diffractive microlens array produced by Coligh is a microarray structure manufactured using the diffractive optical principle. It consists of multiple diffractive microlenses arranged in a two-dimensional square matrix. It can correct high-order phase differences, achromatic aberrations, and achieve arbitrary wavefront modulation through surface relief structures, and realize the functions of controlling the phase of the incident light, focusing, splitting, multi-focus generation, and wavefront shaping of the light beam. Its application range is imaging and beam transformation, optical communication, medical cosmetology, and modulation of arbitrary spot distribution.- Microlens Shape: Square
- Lens Arrangement: Square Grid
- Lens Type: Refractive, Plano-Convex
- Pitch Accuracy: ± 1 μm
