Description
Hexagonal Diffractive Microlens Arrays
The hexagonal diffraction microlens array produced by Coligh using photolithography technology is a two-dimensional micro-array lens in which the shape of a single lens is a regular hexagon and the lenses are arranged in a honeycomb hexagonal arrangement in the array. The microlens array can achieve the purpose of controlling the phase of light waves through the design of this diffraction structure.
Microlens Shape: Hexagonal
Lens Arrangement: Hexagonal Grid
Lens Type: Refractive, Plano-Convex
Pitch Accuracy: ± 1 μm
Applications: Fiber Coupling, Calibration, Imaging

Features
- Compared with the traditional square arrangement, the filling factor is higher and can cover the entire optical surface.
By controlling the phase of the light wave, it can be used for imaging focusing or beam expansion. - The arrangement of the hexagonal diffraction microlens array can form a honeycomb structure. The light uniformity of the honeycomb structure is extremely high in all directions, without obvious edge effects and no overlap in the spot distribution.
- For the diffraction microlens array, we support high-density dot array arrangement, and the highest dot array can support 33*33 dots with uniform output.
Our diffraction lens array can support the design of multi-order structure. The current standard product supports 8-order phase and can support 8-order and above continuous phase, so as to achieve the purpose of multi-focus focusing and multi-wavelength beam splitting.
Applications
- Multicolor fluorescence microscope: In multicolor fluorescence microscope, multi-order diffraction structures can be used to focus or split different wavelengths separately, and multiple fluorescent markers can be imaged simultaneously in a single optical path to improve imaging efficiency
- AR/VR: The diffraction structure of the diffraction microlens can control the light angle, realize angle shaping, and homogenize the light output, which can provide efficient and uniform illumination
- Optical communication: The diffraction microlens array can focus the laser beam to the fiber array port and waveguide port for fiber coupling. At the same time, angle offset compensation or wavefront shaping can also be performed to realize the simultaneous verification function of collimation and coupling.
