Features
Its Key Features Below:
- We use advanced photolithography and etching equipment for production. This refractive microlens array features square apertures arranged in a square grid, providing uniform beam shaping and homogenization to ensure stable laser system output.
- UV fused silica itself has excellent transmission, high-temperature resistance, and laser damage resistance. Besides UV fused silica, we also offer silicon substrates for microlens array fabrication.
- We currently have a large inventory. The smallest unit aperture can reach 10 µm, and the largest unit aperture can reach 1500 µm. Besides standard sizes, the minimum overall diameter can be as small as 1.5 mm, and the maximum diameter can be up to 4 inches.
- The conventional energy efficiency is generally above 70%, and can be customized to 80–90%.
- The designed center wavelength depends on the customer’s system. Standard center wavelengths include 632.8 nm, 808 nm, 1545 nm, 1030 nm, 520 nm, 550 nm, 650 nm, 1064 nm, 1550 nm, 633 nm, 455 nm, 976 nm, 975 nm, meeting common laser system requirements. Coatings can be customized within the 200 nm to 20 μm range. It is suitable for quick prototype building.
Applications
- Microlens Arrays for Medical Aesthetics
In the medical aesthetics field, microlens arrays are mainly used in laser beauty treatments, skin therapy, laser hair removal systems, and photorejuvenation. Fused silica microlens arrays can be applied in picosecond, nanosecond, and long-pulse medical devices. The microlens arrays can evenly distribute laser energy and improve laser coupling efficiency. - Fused Silica Microlens for Laser LIDAR
In applications such as drones and autonomous vehicles, fused silica microlens arrays can split the emitted laser beam into multiple smaller beams, distributing and collimating the beams uniformly. Additionally, in multi-channel optical designs, microlens arrays can achieve beam focusing and separation. - Microlens Arrays for Infrared Imaging
In infrared imaging, microlens arrays can focus more infrared radiation onto the detector units. Moreover, microlens arrays can improve the spatial sampling of detector pixels. Efficient light collection and focusing help microlens arrays assist in forming clearer images.
