PLANO/CONCAVE, PLANO/CONVEX
Cylindrical lenses focus incoming light in one dimension only, such
as in transforming a point image into a line image or changing the height
of an image without changing its width or vice versa.
RMI Lenses are designed at customer wavelength.
Additionally, both sides can be coated with an RMI high efficiency narrowband,
anti-reflective coating.
Square Cylindrical Lenses and Double Sided Aplanats are also available-call
