LBTEK Plano-Concave Circular Cylindrical Lens features one flat surface and one concave cylindrical surface, with a negative focal length. Unlike spherical lenses, cylindrical lenses act on the light beam in only one direction. Cylindrical lenses are commonly used for beam shaping, with typical applications including collimation using dual cylindrical lens assemblies and circularizing the output beam of laser diodes. To minimize spherical aberration, when using plano-concave circular cylindrical lenses to diverge a collimated beam into a spot, the beam should be incident on the curved surface of the lens. LBTEK selects lenses made from UVFS, which are widely used in applications ranging from ultraviolet to near-infrared wavelengths. LBTEK offers uncoated plano-concave circular cylindrical lenses as well as two types of anti-reflection coated lenses for 245-400 nm and 350-700 nm ranges. All our lenses undergo precision machining and strict quality control to ensure high-quality products at reasonable prices for our customers.

Plano-concave cylindrical lens, UVFS, uncoated: 190 nm-2.1 μm

• Material: UVFS
• Circular geometry, mounted in mechanical housing
• Wavelength Range: 190 nm-2.1 µm (uncoated)

LBTEK plano-concave cylindrical lenses are ideal for one-dimensional magnification applications. Unlike spherical lenses, cylindrical lenses act on the light beam in only one direction. Typical applications include collimating and circularizing laser diode output beams using dual cylindrical lens setups. Unlike standard plano-concave lenses, these plano-concave cylindrical lenses are mounted in anodized black aluminum alloy retaining rings with a diameter of 25.4mm, making them easy to integrate with standard SM1 lens tubes or 25.4 mm lens mounts.
