A plano concave cylindrical lens is an optical lens with one flat surface and one inwardly curved cylindrical surface.
Unlike common lens, It affects light only in one direction.
This unique feature allows them to expand light into a line, correct astigmatism, or manipulate laser beams in precision optical systems.
Key Features
- Plano-concave design – one flat side and one concave cylindrical side.
- Negative focal length – It causes light rays to diverge in one axis.
- Material options – People can choose in optical glass, fused silica, quartz, and othersubstrates.
- High precision – Manufactured with tight tolerances for laser and imaging applications.
- Custom coatings – AR coatings to enhance transmission in UV, visible, or IR ranges.
Applications of plano concave cylindrical lens
A cylindrical lens is widely used in industries such as optics, photonics, and laser engineering. Here are the main situations:
- Beam shaping – The lens expands laser beams into lines for scanning and illumination.
- Astigmatism correction – Correct beam distortion in imaging or projection systems.
- Optical instruments – The lens improves performance in spectrometers and analyzers
- Laser systems –The plano concave cylindrical lens controls beam profiles for medical, industrial, and scientific lasers.
- Imaging systems –The lens enhances resolution in cameras and machine vision equipment.
With high-quality materials and advanced manufacturing, these lenses ensure reliable optical performance in demanding environments.
