Cylindrical lens beam shaping
WebA cylindrical lens is a lens which focuses light into a line instead of a point, as a spherical lens would. The curved face or faces of a cylindrical lens are sections of a cylinder, … WebApr 13, 2024 · The focal lengths of the cylindrical lenses were f 1 = f 2 = 200 mm, the propagation distance between the source field and the first cylindrical lens was z 0 = 500 mm. Due to the size of the lens holder, the cylindrical lenses cannot be too close, so the distance between two the cylindrical lenses was s = 60 mm.

Powell lenses are lenses that create a straight laser line by dispersing, in a controlled way, an input collimated beam. ... It is possible to create a laser line using cylindrical lenses, however, the intensity profile of such a line will have a Gaussian-like distribution ...
WebJun 1, 2005 · A field lens and a slit mask are included. The slit can be used to clip the edges of the beam profile in the narrow axis, ensuring very sharp edges, if required by the application. The homogeneous beam is then imaged by a projection lens, which is a cylindrical doublet that reduces the short axis down to 0.4 mm. WebIn 3D PALM/STORM, a type of optical super-resolution microscopy, a cylindrical lens can be introduced into the imaging system to create astigmatism, which allows measurement of the Z position of a diffraction-limited light source. Laser line levels use a cylindrical lens to spread a laser beam from a point into a line. See also
