Frequently Asked Questions
Cylindrical lenses are used to correct astigmatism in the eye and in rangefinders, to produce astigmatism, stretching a point of light into a line. They are widely used in bar code scanning, projection optics systems, laser measurement systems, and holography.
Plano-concave lenses have a negative focal length and are used for image reduction or to spread light. Plano-convex lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.
The specifications for cylindrical lenses include diameter tolerance (mm), focal length tolerance (mm), centration, surface quality, and bevel. Coating is also available upon request.
The typical materials used for cylindrical lenses are N-BK7, H-K9, Fused Silica, N-SF10, etc.
Cylindrical lenses are available in either plano-concave or plano-convex configurations.
