Standard Microlens Array

Standard Microlens Array

A microlens array is an array of a plurality of micro-sized lenslets of the same shape arranged in a regular pattern, the pattern could be square or hexagonal. The subunit size of Most standard products is 32μm-1500μm and the focal length is between 0.8mm-50mm. The shape of each subunit could be square, hexagonal or round. The microlens array (Fly-eye Lenses) is generally used in Hartmann wavefront sensor (HSWFS), laser homogenization, beam splitting, wavefront Sensing, beam focusing and collimation.

The microlens array is an array of a plurality of micro-sized lenslets of the same shape arranged in a regular pattern. The shape of the lenslets may be circular, square, hexagonal, square or other shapes, most of which are in a square grid. They can also be arranged in square, hexagon or other shapes. Microlens are characterized by miniaturization, integration, and design freedom. It enables laser homogenization, beam splitting and beam focusing, Hartmann wavefront sensor (HSWFS), collimation, wavefront sensing and more. Generally used in high sensitivity imaging, fiber-coupled communication, laser beauty, laser processing and detection.

 

Main parameters of the microlens array:

1. The size and material of the microlens

2. The shape of the microlens, cylindrical lens, spherical mirror, aspheric lens, non-cylindrical lens, astigmatic lens

3. Arrangement of microlenses: square array, hexagonal arrangement, 啁啾 arrangement, random arrangement, etc.

4. Microlens cycle (subunit diameter), focal length, etch depth (height), radius of curvature

5. Surface shape: For diffractive elements, there are generally two types of continuous surface type and discontinuous surface shape (step type). The continuous surface type can eliminate chromatic aberration and is suitable for applications such as wide-band system imaging and spiral phase plate.

For the above parameters, we can provide customization.

Micro lens array processing capability, customization ability

Years of precipitation, we have accumulated a wealth of experience in the mask, etching, micro-optical surface technology, through the standard design, processing flow, usually only one month to allow users to achieve satisfactory results customized product.

1. The range of the microlens covers the range of 190nm~10600nm, matching the wavelengths of various common lasers.

2. It can process not only stepped microlenses of 2~32 steps, but also various continuous surface type microlenses. At present, the processes of 2 steps, 4 steps, 8 steps, 16 steps and 32 steps are very mature, and the diffraction efficiency can be 95%. For continuous surface structure, we can achieve numerical aperture: 0.01~0.5, surface error: <2%.

3. The size of each tiny lens/subunit can be as small as 1um, usually between 1 and 5000um, and the shape can be circular, square, rectangular, hexagonal or other user-specified shapes.

4. The material of the microlens is generally selected from plastic materials such as glass, quartz, tantalum, zinc selenide (ZnSe), silicon, K9, calcium fluoride or PMMA.
