Custom High Precision Optical CaF2 K9 Fused Silica Plano Convex Cylindrical Lens

Name: Custom High Precision Optical CaF2 K9 Fused Silica Plano Convex Cylindrical Lens
Brand: Henan UM Optics Ltd
Availability: InStock

Description

Cylindrical lens are generally used to converge parallel or diverging beams to a line or to change the aspect ratio of an image. Cylindrical lens can be divided into two structures: plano-convex and plano-concave, both of which are used to converge or diverge beams, respectively. A wide range of materials and coatings of Cylindrical lens are available for UM OPTICS, such as CaF2, K9, UVFS, Si, Ge and ZnSE, to meet different customer needs.

Features

Asymmetrical Surface Design: One flat surface + one convex cylindrical surface, focusing incident light into a linear beam (instead of a point) for directional light shaping
Broad Material Compatibility: Available in CaF2,K9, fused silica, ZnSe, etc., to match UV/visible/IR wavelength requirements
High Transmittance: Precision-polished optical surfaces (Ra ≤ 0.01μm) ensure minimal scattering loss
Anti-Reflection (AR) Coating Option: Customizable coatings to reduce surface reflection and boost light utilization efficiency
Tight Dimensional Tolerance: Controlled within ±0.01mm for stable integration into optical systems
Environmental Stability: Resistant to temperature fluctuations (especially with fused silica) to avoid optical distortion
Customizable Specifications: OEM/ODM support for size, curvature, and coating parameters

Applications

Laser Beam Shaping: Generates linear laser beams for laser cutting, scribing, and line scanning systems
Optical Printing & Scanning: Used in barcode readers and laser printers to shape light for clear line imaging
Medical Imaging: Integrated into slit lamps and endoscopes to form linear light sources for tissue observation
Industrial Metrology: Applied in profile projectors and optical comparators to project linear light for dimension measurement
