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
