Features
- The lens shape is a circular lens array, and it adopts a square arrangement, supporting spherical or aspherical design
- We use advanced photolithography technology to control the key optical parameters of the lens, such as size, array, focal length, etc., which is higher than the ordinary molding precision.
- We have two materials to choose from, fused quartz and single crystal silicon, which can meet the needs of ultraviolet, visible light or infrared bands
The standard sub-unit aperture is optional from 26.5um to 500um, and we can customize the array pitch of 10um-1500nm. - The standard center wavelengths are 532nm, 632.8nm, 1550nm, 1064nm, 850nm, 940nm. It can meet most laser wavelength requirements
Applications
- Laser Shaping
The light spot output by a high-power laser usually has uneven energy distribution and irregular shape. By placing the microlens array in front of the laser output end, the uniform shaping, collimation and divergence angle of the beam can be controlled - Laser Medical Aesthetics
In medical aesthetics, medical aesthetics laser systems such as hair removal, skin rejuvenation, picosecond and dot matrix beauty have high uniformity of laser light spot and laser energy. Microarray lenses can achieve uniform laser irradiation and optimize the energy distribution - Lidar
In laser radar equipment such as autonomous driving, robots, mapping, and security, the resolution and accuracy of laser radar are very high. By applying microarray lenses, laser beam splitting, homogenization and light spot shaping can be achieved. - Optical Communication
The optical communication module has high requirements for beam shaping and energy uniformity. The microarray lens can be used as a homogenizer of the light source to improve the signal strength of optical communication
Frequently Asked Questions
Microlens arrays are used in imaging and beam shaping, CCD detection, optical communication, multi-beam scanning, CD or DVD read/write heads, and medical and beauty devices.
Refractive microlens arrays offer smaller size, lighter weight, and higher integration while addressing challenges in processing high-order aspherical and freeform surfaces, small curvature radii, and small apertures.
The microlens arrays are made from fused silica.
The typical wavelength range for these microlens arrays is around 0.6328μm and 0.808μm, with some products specified for 1.545μm.
The pitch range for the microlens arrays varies from 10.0μm to 100.0μm.
The numerical aperture (N.A.) indicates the range of angles over which the system can accept or emit light, influencing the resolution and brightness of the optical system.
