Description
Cylindrical lenses are used to correct astigmatism in the eye and
in rangefinders, to produce astigmatism, stretching a point of
light into a line. Some styles of cylindrical lenses have
antireflective coatings to increase the transmission of light
through the lens.
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 ,
