Overview of Plano Concave Cylindrical Lens

The ATOPTIK Plano-Concave Cylindrical Lens is a negative cylindrical lens designed to diverge light into a line rather than a point, unlike a spherical lens. This unique optical property makes it an essential component in applications requiring linear light divergence. The curved surface of the lens forms part of a cylinder, causing the transmitted light to focus along a line parallel to the intersection of the cylindrical surface and its tangent plane.

Features of Plano Concave Cylindrical Lens

Plano-Concave Structure
This lens features a single flat surface and a single concave cylindrical surface, which creates a negative focal length. It works by diverging light along a single axis, making it ideal for controlling astigmatism, beam shaping, or other applications requiring precise linear light control.
Circular Edging for Easy Integration
The ATOPTIK Plano-Concave Cylindrical Lens is edged into a circular shape, allowing it to be easily combined with other optical elements to form more complex systems.
Uncoated Design with Optional Coatings
The lenses are supplied in their standard uncoated version to maintain flexibility for different applications. For enhanced performance, anti-reflection (AR) coatings are available upon request. Customers with specific coating requirements can contact the ATOPTIK sales team for further details.
