These lenses have positive focus length. Most suitable where one conjugate is more than five times, the other. e.g. in sensor application or for use with near collimated light. Also where both conjugates are on the same side of the lens, e.g. as an add-on lens to increase the numerical aperture.

Cylindrical Lens
Cylindrical lens is used to provide focusing power in one section only. For illumination or detection of light from line sources. Also used to anamorphic compression of beams and images. Especially widely used to anamorphic compression of LD (laser diode) output beam.

Meniscus Lens
Meniscus Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly
