Introductions
Microlens array enables laser homogenization, beam splitting and beam focusing, Hartmann wavefront sensor (HSWFS), collimation, wavefront sensing, and more. It is generally used for high-sensitivity imaging, fiber-coupled communications, laser cosmetology, laser processing and inspection.
Customization capability
-Microlens materials: Fused Silica, Si, Ge, Resin, Polymer.
-The main technologies are mask photolithography + etching methods and nanoimprint lithography (NIL).
-Customizable double-sided microlens with alignment accuracy<2um.
-The shape of microlens subunits could be circular, square, or hexagonal.
-Microlens elements can be cut according to the shape and size specified by the user.
-With or without AR coating.
-Microlens gap can be chrome plated.
Note: The ML series microlens array are cost-effective product line. Mainly used for Medical beauty, Shack Hartmann sensor, High sensitivity imaging, Wavefront sensing, Beam focusing and some other applications. Due to the limited level of our cleanroom in old factory, there are always some defects (bad spots) on the surface of ML series products. The surface accuracy is also not very good.
The MLA, MLA1 and CLA, CLA1 series are high-end product line. MLA, MLA1 and CLA, CLA1 series microlens array have more accurate surface and less surface defects. They could be used for different applications, such as beam shaping (beam homogenization) and Industrial grade light field camera.
