  • These lenses are also available uncoated or with a -B or -C antireflection coating.
  • Uncoated Wavelength Range: 350 nm - 2.0 µm
  • Much like surface flatness for flat optics, surface power is a measure of the deviation between the surface of the curved optic and a calibrated reference gauge, typically for a 633 nm source, unless otherwise stated. This specification is also commonly referred to as surface fit.

Features

  • Made of N-BK7 Glass
  • AR Coating Wavelength Range: 350-700 nm
  • Focal Lengths from -3.9 mm to -1000.0 mm
  • Focal Length Tolerance: ±1%

Negative cylindrical lenses act as plano-concave spherical lenses, except on only one axis. These lenses are used in applications that require one dimensional shaping of a light source. A typical application is to use a single cylindrical lens to turn a collimated laser into a line generator. Pairs of cylindrical lenses may be used to anamorphically shape images. To minimize the introduction of abberation, the curved surface of the lens should face the source when used to diverge a beam.

For cage system and lens tube compatibility, please see our Mounted Plano-Concave Round Cylindrical lenses. These lenses are typically easier to integrate into our standard optomechanics.

All cylindrical lenses can be ordered uncoated and the cylindrical lenses made from BK7 can be ordered with one of the following broadband AR coatings:
-A: 350-700 nm, -B: 650-1050 nm or -C:1050-1620 nm

These high performance multilayer AR coatings have an average reflectance of less than 0.5% (per surface) across the specified wavelength ranges. The central peak in each curve is less than 0.25%. These coatings are designed for angles of incidence between 0 and 30 degrees (0.5 NA). For optics intended to be used at large angles, consider using a custom coating optimized at a 45 degree angle of incidence; these coatings are effective from 25 to 52 degrees. The plot shown below indicates the performance of the standard coatings in this family as a function of wavelength. Broadband coatings have a typical absorption of 0.25%, not shown in the reflectivity plots.
