Custom Fused Silica Plano Convex Cylindrical Lens

Fused Silica Cylindrical Lenses Product Description

Plano-convex cylindrical lenses feature curvature along a single axis, enabling the modification of beam convergence or divergence in one dimension and transforming circular spots into uniform linear profiles. Asin Optics manufactures and customizes fused silica plano-convex cylindrical lenses; utilizing UV-grade fused silica substrates combined with precision polishing and high damage-threshold capabilities, these lenses are specifically designed for one-dimensional beam shaping while addressing issues such as generatrix tilt and decentration errors. They are widely used in applications including laser beam shaping, spectrometer illumination, and LiDAR. We offer services ranging from prototype development to high-volume OEM production.

Custom Laser Grade Plano-Convex Cylindrical Lenses Core Technical Advantage

1. We currently offer a variety of high-purity substrate materials, such as BK7, fused silica, calcium fluoride, and zinc selenide. For high-power laser applications, we utilize high-purity fused silica that maintains high transmission across the 185 nm to 2.1 μm range; its low thermal expansion coefficient ensures focal length stability even under kilowatt-level laser irradiation.
2. We operate our own in-house coating facility capable of producing multilayer broadband anti-reflective (AR) coatings for the visible to near-infrared spectrum. Additionally, we can apply high-laser-damage-threshold AR coatings optimized for specific wavelengths—such as 355 nm, 532 nm, and 1064 nm—suitable for use in high-power laser systems and pump beam shaping.

Applications Of High-Precision Rectangular and Round Cylindrical Lenses

 

Laser Diode Collimation

Edge-emitting laser diodes exhibit astigmatism and asymmetric divergence angles; consequently, their raw output beams cannot be directly coupled into optical fibers. A collimating lens designed for laser diodes can act independently on the fast axis—or work in conjunction with a spherical lens or a second cylindrical lens—to transform the asymmetric, diverging beam into a circular, collimated output.

Anamorphic Beam Shaping

Applications such as laser display, printing, large-area annealing, and lithography illumination require shaping an input circular Gaussian beam into a line, ellipse, or rectangle with a flat-top profile, while also necessitating independent control of beam dimensions and divergence angles in two orthogonal directions. Anamorphic beam-shaping cylindrical optics achieve this by independently expanding or compressing the beam along the X and Y axes.

1064nm Line Laser

Industrial machine vision, 3D profile scanning, and structured light measurement require high-brightness, uniform 1064nm line illumination. Lenses designed for generating 1064nm line lasers can directly focus a collimated 1064nm laser beam into a slender focal line capable of handling high laser power.
