Key Features

1. Single-Axis Curvature: Optical power is applied in one dimension (e.g., X or Y axis), while the perpendicular axis remains planar.

 

2. Asymmetric Light Shaping: Convert collimated light into a line or sheet, or transform elliptical beams (e.g., laser diodes) into circular profiles.

 

3. Types:

Plano-Convex/Concave: One curved surface, one flat.

Biconvex/Concave: Curved surfaces with radii in the same axis.

Achromatic: Paired elements to reduce chromatic aberration.

Applications

Astigmatism Correction: In ophthalmology, toric lenses (a form of cylindrical lens) correct corneal astigmatism.

 

Laser Beam Circularization: Reshape elliptical diode laser outputs into symmetric beams.

 

Line Illumination: Generate uniform light sheets for barcode scanning, machine vision, or medical imaging (e.g., OCT).

 

Spectroscopy: Focus light onto slit apertures or linear detector arrays.
