| Product Summary: |
Features
- Made of N-BK7 Glass
- Collimates & Circularizes the Output of a Laser Diode
- AR Coated Wavelength Range: 650 - 1050 nm
This positive cylindrical lens is ideal for applications requiring magnification in one dimension. While the spherical lens acts symmetrically in two dimensions on an incident ray, the cylindrical lens acts in the same manner but only in one dimension. A typical application is to use a pair of cylindrical lenses to provide anamorphic shaping of a beam. A pair of positive cylindrical lenses can be used to collimate and circularize the output of a laser diode. Another application possibility would be to use a single lens to focus a diverging beam on to a detector array. To minimize the introduction of spherical aberrations, collimated light should be incident on the curved surface when focusing it to a line and light from a line source should be incident on the plano surface when collimating.
