Product Family Description

  • Cylinder Lenses Ideal for 1 Dimensional Laser Beam Convergence
  • Circular and Rectangular Form Factors
  • Multiple Coating Options Available

Illumination PCV Cylinder lenses are commonly used to turn a collimated laser source into a line generator. PCV and PCX oblong 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 * (r0/f) * (z + f) where L is the line length, r0 is half the beam diameter, z is the projection distance, and -f is the focal length of the lens.
