High Performance Cylinder Lenses
Description
Focuses light in only one dimension. Similar to a PCX lens in profile, but is a portion of a cylinder instead of a sphere. Cylinder lenses can transform a point of light into a line image. This is useful for making laser line generators. The lens magnifies in one dimension so it can be used for stretching images. Can be used for focusing light into a slit or converging light for a line scan detector. Due to a tighter tolerance on tilt and wedge, high performance imaging lenses will give straighter lines and better images than our standard cylinder lenses.

Frequently Asked Questions
The common specifications for cylinder lenses include dimensional tolerance, center thickness tolerance, substrate material (N-BK7), focal length tolerance, and surface quality.
High performance cylinder lenses have tight tolerances on tilt and wedge, higher image quality than standard cylinder lenses, and use N-BK7 substrate for broadband performance.
A cylinder lens is a portion of a cylinder, while a PCX lens is a portion of a sphere. Both lenses can focus light, but a cylinder lens magnifies in one dimension and can be used for stretching images.
A cylinder lens is used to transform a point of light into a line image, which is useful for making laser line generators.
The different coatings available for cylinder lenses can enhance their performance in specific wavelength ranges, such as MgF for 400-700nm or VIS-NIR for 400-1000nm.
