25mm Dia x -100mm FL Uncoated, Illumination Grade PCV Cylinder Lens

Product Details Cylinder Lenses Ideal for 1 Dimensional Laser Beam Convergence Circular and Rectangular Form Factors Multiple Coating Options Available TECHSPEC Illumination Grade PCV Cylinder Lenses are commonly used to turn a collimated laser source into a line generator. These PCV Cylinder Lenses and TECHSPEC Illumination Grade PCX Cylinder Lenses can be used together for beam expander applications. The thin lens approximation for the length of a line generated by a negative cylinder lens is: L = 2 * (r 0 /f) * (z + f) where L is the line length, r 0 is half the beam diameter, z is the projection distance, and -f is the focal length of the lens.
