A meniscus cylindrical lens features one convex and one concave cylindrical surface, engineered to focus or diverge light in a single dimension. This asymmetric profile optimizes optical performance while minimizing system complexity, ideal for compact, high-precision setups.

- Aberration Correction: The convex-concave curvature suppresses spherical aberration and astigmatism far better than standard plano cylindrical lenses, delivering sharper line foci and uniform beam profiles.
- Increased NA & Light Efficiency: Boosts system numerical aperture (NA) with minimal added aberration, enhancing light gathering and resolution for low-light or high-speed applications.
- Single-Axis Focus: Creates a crisp, straight focal line (not a point) for laser line generation, beam collimation, and anamorphic shaping—perfect for laser diodes, scanners, and imaging systems.
- Broad Material & Coating Options: Available in BK7, fused silica (UVFS), CaF₂, ZnSe, and sapphire; with AR coatings for UV (245–400 nm), visible (350–700 nm), or NIR (650–1050 nm), ensuring >99% transmission and minimal ghosting.
The Applications of Cylindrical Lenses
Laser beam shaping, diode laser circularization, astigmatism compensation in imaging, barcode scanning, spectroscopy, medical optics (endoscopes), and industrial laser processing.
- Aberration Correction: The convex-concave curvature suppresses spherical aberration and astigmatism far better than standard plano cylindrical lenses, delivering sharper line foci and uniform beam profiles.
