Cylindrical Lenses Types of Cylindrical Lenses. A cylindrical lens is characterized by both its focal length and its geometry. They can be square, circular, or rectangular. A plano concave cylindrical lens will expand light on a single axis. It is also known as a negative cylindrical lens, and is used for one-dimensional image compression, anamorphic beam shaping, and laser line generation. A plano convex cylindrical lens focuses light on one axis, and can also be used to magnify an image in one direction... (read more)Browse Optical Lenses Datasheets for Avantier Inc. -

Acylindrical Lenses Benefits of Acylinder Lenses. An acylindrical lens is designed to be highly efficient and to deviate from a true cylinder in such a way as to minimize the optical aberrations in a given system. Using acylinder lenses in a system often provides the opportunity to reduce the number of optical components, thus decreasing the size and weight of an optical system. Acylinder lenses also provide ideal collimation and the sharpest possible line focus in many circumstances. Applications of Acylindrical...

The angularly dispersed first order beams are collimated using an achromatic doublet ( Melles Griot 06 LAI007) upon the measurement mirror. The beams are reflected back from the measurement mirror and then re-trace their path back to the grating where they interfere with the returning zero order beam and are incident upon the GRIN lens afterwhich they re-enter the fibre.
