Description
Cylindrical lens is used to correct astigmatism in the eye, and, in
rangefinders, to produce astigmatism, stretching a point of light
into a line.They are available in either plano concave or plano
convex configurations. Plano-Concave Cylindrical lenses have a
negative focal length and are used for image reduction or to spread
light. Plano-Convex Cylindrical lenses have a positive focal
length, which makes them ideal for collecting and focusing light
for many imaging applications. Â Every sizes,materials
cylindrical lenses are available according to your detailed
parameters.
We supply kinds of plano-convex cylindrical lens,plano-concave
cylindrical lens,bi-convex cylindrical lens,bi-concave cylindrical
lens,meniscus cylindrical lens,Rod cylindrical lenses,special
cylindrical lens etc..
