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 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 available for the cylindrical lens?
The cylindrical lens is available in materials such as BK7, FS, UVFS, CaF2, ZnSe, Si, and Ge.
What is the diameter range for the cylindrical lenses?
The diameter of the cylindrical lenses ranges from 3mm to 300mm or larger.
What is the diameter tolerance for the lenses?
The standard diameter tolerance is +0.0/-0.2mm, while the high precision diameter tolerance is +0.0/-0.1mm.
What is the surface quality of the lenses?
The standard surface quality is 60-40 S-D, while the high precision surface quality can be 40-20 or 20-10 S-D.
Are coatings available for the lenses?
The lenses are uncoated by default, but coatings are available upon request.
