Ecoptik of Optical Cylindrical Lens

07 May 2022

A cylindrical optical lens is typically used to focus, condense or expand incoming light. A cylindrical optical lens has one cylindrical surface, causing light to be focussed in a single dimension or axis.  It can also be used to expand the output of a laser diode into a symmetrical beam. Cylindrical optical lenses are technically more difficult to manufacture than spherical or flat lenses which is why Ecoptik (also known as BRD Optical) uses state-of-the-art polishing techniques alongside stringent lens assessment to manufacture each lens.

A cylindrical optical lens is typically rectangular, square, or circular and of either a plano-convex or plano-concave design. The cylindrical optical lenses of Ecoptik (also known as BRD Optical) combine low wedge with high surface accuracy. As one of the best optical components manufacturers, we assess the quality of each individual lens using Trioptics centration measurement and a Zygo GPI interferometer.  All Ecoptik lenses are available both uncoated or coated with a broad range of high durability, low loss AR coatings, and can be manufactured to 20-10 surface roughness. 

Cylindrical optics lens can converge or diverge 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 widely used 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.
