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. earth tiger tarantulaWebNov 11, 2024 · This post will review a method for beam shaping using Powell Lenses. 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 ... earthtilesWebCollimation of such beam with a single lens makes the beam elliptical. In some operations, a rounded beam cross-section is much more desired than an elliptical shape beam. Usually, the first idea for collimating and circularizing a beam emitted by a semiconductor laser is to use two orthogonally positioned cylindrical lenses.
