Rod lenses, as indicated by the name, is a special cylindrical lenses with cylindrical surface and two ends polished. Light incidents in the side of the lenses and got collimated in one dimension.

Double Convex Cylindrical Lenses, as indicated by the name, is a special cylindrical lenses with two convex surfaces. Usually the two convex surfaces do not have the same x and y axis thus it can be used to change the aspect ratio of the image.

Double Concave Cylindrical Lenses, as indicated by the name, is a special cylindrical lenses with two concave surfaces. Usually the two concave surfaces do not have the same x and y axis thus it can be used to change the aspect ratio of the image. It is a

Plano Convex Cylindrical Lenses, as indicated by the name, is a special cylindrical lenses with one flat surface and one convex surface. Unlike spherical lenses, which converge light into a spot, Plano Convex Cylindrical Lenses converge light into a line.

Plano Concave Cylindrical Lenses, as indicated by the name, is a special cylindrical lenses with one flat surface and one concave surface. Unlike spherical lenses, which converge light into a spot or expand a spot in two dimensions, Plano Concave Cylindri
