Description

Our Cylindrical Lenses are expertly designed to focus light into a line rather than a point, making them ideal for applications requiring precise image manipulation. These lenses converge or diverge light in the direction perpendicular to the cylindrical axis, while maintaining the image integrity along the tangent plane.

Frequently Asked Questions

What is a cylindrical lens?
A cylindrical lens is a lens that focuses light into a line instead of a point, as a spherical lens would. It converges or diverges the image in the direction perpendicular to this line and leaves it unaltered in the direction parallel to its cylinder's axis.
What materials are cylindrical lenses made from?
Cylindrical lenses can be made from materials such as BK7, FS, UVFS, CaF2, ZnSe, Si, and Ge.
What are the diameter specifications for cylindrical lenses?
The diameter of cylindrical lenses ranges from 3mm to 300mm or larger, with a diameter tolerance of +0.0/-0.2 mm for standard lenses and +0.0/-0.1 mm for high precision lenses.
What is the surface quality of cylindrical lenses?
The surface quality of standard cylindrical lenses is 60-40 S-D, while high precision lenses have a surface quality of 20-10 S-D.
What is the surface flatness of cylindrical lenses?
The surface flatness of standard cylindrical lenses is 1 λ @ 632.8 nm, and for high precision lenses, it is 1/4 λ @ 632.8 nm.
Are coatings available for cylindrical lenses?
Cylindrical lenses are uncoated by default, but coatings are available upon request.
