Linear Bar Lights can be used for a wide range of solutions. Bar Lights are some of the most versatile and widely used lights in machine vision. Bright Field and Dark Field illumination can be created by adjusting the pitch of mounting. Machine Vision Direct offers various colors and lenses to produce the appropriate illumination for each application

Line-Scan Cameras: In line-scan cameras used in industrial applications, such as quality control in manufacturing, cylindrical lenses help create a narrow line of light that is scanned across the object being inspected.

Printing and Labeling: Cylindrical lenses can be used in printing and labeling machines to ensure precise control of the printing process.

Material Processing: In laser material processing applications, cylindrical lenses are used to shape laser beams for cutting, engraving, and welding. They can also be used to create elongated heat zones for selective material treatment.

Anamorphic Prism Pairs: Cylindrical lenses are combined with prisms to create anamorphic prism pairs, which are used in beam shaping and expansion in laser systems. They can be used to change the elliptical shape of a laser beam into a circular one.

Machine Vision and Inspection: Cylindrical lenses can be used in machine vision systems to create a line of light for inspections and measurements in manufacturing processes.

Applications where light needs to be focused into a line, or the aspect ration of an image needs to be changed, utilize cylindrical lenses. The single cylindrical surface causes incoming light to be focused in a single dimension, ultimately stretching the image. Cylinder lenses come with positive or negative focal lengths, ideal for laser line generation or anamorphic beam shaping to circularize laser outputs.

A cylindrical lens focuses light into a line, as opposed to a spherical lens that focuses light into a single point. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to the intersection of the surface of the lens and a plane tangent to it. The lens compresses the image in the direction perpendicular to this line, and leaves it unaltered in the direction parallel to it (in the tangent plane).

Barcode Scanners: Cylindrical lenses are used in barcode scanners to create a one-dimensional laser line that can quickly read the barcode as the scanner is moved across it.

Machine Vision Direct is an authorized distributor of Smart Vision Lights, a leading industrial machine vision lighting supplier. When you contact us, our engineers answer the phone and are more than happy to assist you in picking the vision system or accessories that best suit your system. You can even send us application images and details to have us assist in picking out an appropriate vision system.

Machine Vision Direct offers Smart Vision Lights generous 45 day trial period. Contact us if you are interested in trying a light.

Microscopy: In some microscopy techniques, cylindrical lenses are used to shape the illumination or to create specific patterns of light for applications like laser scanning confocal microscopy.

Optical Character Recognition (OCR): OCR systems use cylindrical lenses to create a thin line of light to improve the accuracy of text recognition by illuminating one line of characters at a time.

Astigmatism Correction: In optical systems where astigmatism is a problem, cylindrical lenses can be used to correct the astigmatic aberration by focusing the light in one direction and defocusing in the perpendicular direction.
