Micro Lens Array

Name: Micro Lens Array
Brand: ECOPTIK INDUSTRIAL PTE.LTD.

Micro lens array is an array composed of lens with aperture and embossed depth of micrometer. It not only has the basic functions of traditional lens such as focusing and imaging, but also has the characteristics of small unit size and high integration, which enables it to complete the functions that traditional optical elements cannot complete and can constitute many new optical systems.

The core value of micro lens arrays lies in miniaturization integration, dynamic controllability, and multi scene adaptability, making them an intelligent vehicle AR/VR、 Key enabling technologies in high-end manufacturing, precision medicine, and other fields.

Features of Micro Lens Array

Substrate: Fused silica, Quartz, ZnSe, Silicon, BK7 glass, etc.
Structure: Spherical lens, aspherical lens, cylindrical lens, etc.
Arrangement square array square lens, square array round lens, hexagonal arrangement, random arrangement, etc.
Micro lens cycle (subunit diameter), focal length, etch depth (height), radius of curvature
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.

Description of Standard Micro Lens Array

The micro lens 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. Micro lens 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.
