Optical Cylindrical lens Optical Glass Plano Convex Cylindrical Lens A Optical glass Cylinder Lenses is used to condense light in one axis. A positive cylindrical lens is able to create a line image from a point of light, to change the aspect ratio of an image or to focus collimated input light to a line. Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping.

In general, the relative aperture is constant during zoom.For imaging system, continuous zoom optical system is the best way to solve the problem of large field search and small field resolution. The ratio of the two ultimate focal lengths in the zoom range, namely the ratio of the long focal length to the short focal length, is called magnification ratio, also known as multiplier. In consideration of the secondary spectrum requirements, the plan of the small relative aperture of the long focal length is adopted (that is, the relative aperture also changes during the zoom process). 3.2 The optical system USES a continuous zoom lens with a focal length of 15mm~300mm.

PARAMETER: Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. An Achromatic Lens, which is often designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses.

Optical Cylindrical lens PARAMETER: Meniscus Cylindrical Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens.

BK7 Glass Powell Lens PARAMETER: The Powell lens is a quantum leap forward in line generator performance over the simple cylinder lens. A cylinder lens produces a poorly illuminated line, one limited by the non-uniform, Gaussian laser beam. The Powell lens' rounded roof is in fact a complex two-dimensional aspheric curve that generates a tremendous amount of spherical aberration that redistributes the light along the line; decreasing the light in the central area while increasing the light level at the line's ends. The result is a very uniformly illuminated line used in all manner of machine vision applications; from bio-medical and automobile assembly to chocolate chip cookie production. The Customized Powell Prism resembles a round prism with a curved roof line. The lens is a laser line generator, stretching a narrow laser beam into a uniformly illuminated straight line .
