Overview:

Cylindrical lenses are used to create lines or for beam expansion in one direction. Their optical properties and aberrations correspond to those of spherical optics. Star Optic offers plano-concave and plano-convex cylindrical lenses in rectangular, square, and round form. Rectangular and square cylindrical lenses possess a clearly defined optical axis. Round cylindrical lenses are a bit more difficult to adjust, but can be integrated into standard lens mounts.

Similar to rectangular plano-convex cylindrical lenses, round plano-convex cylindrical lenses are used in the creation of lines. And round plano-concave cylindrical lenses are similar to rectangular plano-concave cylindrical lenes are used in beam expansion. However, and unlike rectangular substrates, these lenses have the advantage that they can be used with standard lens mounts.

Coating Options Of Round Plano-concave Cylindrical Lens:

Star Optic's above standard round cylindrical lenses are uncoated. In order to reduce the amount of light reflected from each surface of the lens, antireflection coatings including singer layer MgF2, multi-layer AR coating, Broadband multi-layer AR coating and Dual wavelength AR coating are also available.

Single Layer MgF2 Coating	Multi-layer Anti-Reflective Coating
Boradband Anti-Reflective Coating	Dual Wavelength Anti-Reflective Coating

Mounting Options for Round Plano-concave Cylindrical Lens:

Like the spherical lesnes, the round cylindrical lenses can be mounted with our fixed or adjustable lens mougnt for an easier operation.
