Overview
Shanghai Optics manufactures custom microlens arrays in 1D and 2D configurations for demanding optical applications. We provide circular, square, hexagonal, and custom geometries with tailored lens pitch, focal length, substrate materials, and optical coatings to meet specific system requirements.
At Shanghai Optics, we manufacture 1D and 2D microlens arrays in various configurations, sizes, and focal lengths. These arrays are manufactured from high-quality fused silica, providing excellent optical performance from 193 nm to 2.5 μm.. The refractive index is 1.561 at 248 nm and 1.444 at 1550 nm, making them suitable for UV, visible, and infrared optical systems.
Using advanced photolightographic techniques and semiconductor processing technologies, Shanghai Optics produces microlens arrays with precise lens positioning and highly accurate lens profiles. We offer custom microlens arrays tailored to customer specifications, including custom geometries, lens pitch, focal lengths, and coatings. Our experienced engineering team provides design consultation and supports projects from prototype development to OEM volume production.
