Microlens array elements consist of lenses with micrometer-scale clear apertures and micro/nanometer-scale relief depths. They provide focusing, imaging, and collimation, with small element size and high integration. Main applications include Shack-Hartmann wavefront sensing, infrared focal-plane detection, CCD array light concentration, LD shaping, laser array scanning, laser displays, fiber coupling, light-field cameras, 3D displays, and digital maskless lithography (DMD). Binary Microlens Arrays Binary microlens arrays use stepped surface profiles to approximate continuous relief structures. Multiple aligned lithography steps using binary masks produce the multilevel structures. Available structural specifications are as follows: Spectral Range：0.248μm ~10μm； Subaperture Shape：Circular, rectangular, regular hexagonal, annular, etc. Sublens Aperture：0.01mm~4mm Lens Material：Quartz, silicon, germanium, zinc selenide, etc. Typical Number of Levels：2、4、8、16 Diffraction Efficiency：75%~95% Wavelength（μm） | Subaperture（μm） | Subaperture Shape | Focal Length（mm） | Array Size | Substrate Size(mm) 1.064 | 275×275 | Quadrilateral | 8 | 30×30 | φ14×3 1.064 | 1000×1000 | Quadrilateral | 30 | 16×16 | φ30×5 0.55 | 1680（Across parallel sides） | Hexagonal | 29.7 | 37×37 | φ14×3 0.5 | 1680（Across parallel sides） | Hexagonal | 69.8 | 7×9 | φ20×3 1.064 | 1750×1750 | Square | 90 | 6×6 | φ20×3 Continuous-Surface Microlens Arrays Our unique forming and surface-profile control technologies produce high-precision continuous-surface microlens arrays without diffractive chromatic aberration for broadband system imaging and focusing.

The following figure shows a specially profiled cylindrical lens structure we developed, with surface-profile accuracy controlled to 50nm, and surface roughness below 10nm。 Quadrilateral Microlens Arrays Quadrilateral microlenses have quadrilateral apertures or are arranged in a quadrilateral pattern. We can customize quadrilateral microlens arrays with apertures from 5μm~5mm.
