Cylindrical Lens Array
Definition: cylindrical microlens arrays are refractive micro-optics comprising many tightly packed one-dimensional cylindrical lenslets periodically arranged along a line. Each has power in one axis only, with no orthogonal convergence/divergence. Unlike spherical arrays focusing in two dimensions, they perform one-dimensional modulation as core integrating beam-shaping/homogenizing optics. See diagram. Parameters: 1. Pitch: center spacing, commonly 50 μm~1 mm; see diagram. 2. EFL: individual cylindrical-lens focal length; see diagram. 3. Fill factor: transmitting-area fraction. 5. Surface: mainly spherical, with aspheric options for precise spherical-aberration correction. Principle: unlike two-dimensional spherical focusing, cylindrical arrays act in one direction, converging parallel light into a bright line or diverging along one axis. See diagram. One-direction focusing with parallel orthogonal transmission converts circular spots to lines. Processing/customization: the company describes itself as an early domestic developer of precision micro/nano optics, with years of research/industrial experience and engineers in optical design, fabrication, and metrology. Experienced microlens-array/diffractive-optics teams solve nonstandard path/process challenges. An integrated proprietary micro/nano lithography line independently produces arrays with stable micrometer pitch precision, leading surface uniformity, nearly full fill factors, and high energy utilization. Fused silica, silicon, germanium, and zinc selenide cover UV-to-far-IR; custom AR/damage-resistant coatings withstand intense lasers and remain stable at high/low temperatures. Teams control simulation, structural optimization, prototypes, mass production, and full optical inspection. Small research/university orders and industrial volumes are accepted. Short delivery and dedicated one-to-one engineering provide rapid commissioning/problem resolution for beam homogenization, Hartmann sensing, and light-field reconstruction. Products are widely mass-applied in Hartmann wavefront sensors, light-field imaging, precision lasers, CCD coupling, and thermal imaging. Precision, stable quality, and after-sales support have earned long-term cooperation from research institutes/listed equipment companies. The company describes itself as among few domestic suppliers independently developing/manufacturing the full microlens-array chain, with technical, capacity, and service support for customization. Page summary: main types are plano-convex/plano-concave cylindrical arrays.
