Optical Cylindrical Lens

Optical cylindrical lens can be used for converging or diverging light beams in a single axis. Cylindrical lens is used in many industries and fields such as optical metrology, laser scanning, spectroscopy, laser diode output beam shaping, and light-sheet illumination microscopic imaging.

• Form the collimated light source into a line light source

  This is the most wide use of cylindrical lens. Taking a plano concave cylindrical lens as an example, it can be a beam of collimated light that expands into a linear light source according to the magnification.

• The cylindrical lens is also used for astigmatism. Collimation of diode output beam The output beam of the laser diode diverges in an asymmetrical form, and its collimation work is more challenging. For example, for a diode light source with a divergence angle, if only a standard spherical lens is used, it can only be collimated in a single direction, and divergence or convergence will occur in the other direction. Using cylindrical mirrors can decompose the problem into two one-dimensional directions. By combining two orthogonal cylindrical mirrors, the two directions can be collimated simultaneously.
