Daheng Optics GCL-11 Cylindrical Lenses CYLINDRICAL LENSES Cylindrical Lenses Cylindrical lenses focus or expand light in one axis only. They can be used to focus light into a thin line in optical metrology, laser scanning, spectroscopy, laser diode, acousto- optic, and optical processor applications. They can also be used to expand the output of a laser diode into a symmetrical beam. Astigmatism An optical system with astigmatism is one where rays that propagate in two perpendicular planes have different foci. If an optical system with astigmatism is used to form an image of a cross, the vertical and...

--Catalog Products & Supplies CYLINDRICAL LENSES If z is large compared to f, then we have an expansion ratio that is very close to z/f. This is not an imaging problem; we are projecting the laser beam into a line at a particular distance. The length of the line is simply proportional to z. If the thinnest possible line is required, a second lens, this one a cylindrical plano-convex lens of focal length ~ z, can be inserted into the system just before or after the plano-concave lens. When oriented on the orthogonal axis, it will focus the laser at the screen onto which the line is projected....

GCL-11 Cylindrical Lenses GCL-1101 Cylinder Plano-Convex Lenses Similar to a Plano-Convex lens in profile, but only as a cylinder instead of a sphere, this cylindrical lens focuses light only in one dimension. It can also transform a point image into a line image or changing the height of an image without affecting its width. There are two circumference shapes, rectangular and circular.
