October 17, 2012. Edmund Optics has introduced new TECHSPEC Hypercentric Lenses. These precision lenses, also called pericentric lenses, are suited for inspecting parts and components in a variety of machine-vision applications.
TECHSPEC Hypercentric Lenses provide a converging view of an object, simultaneously focusing on the top and surrounding sides, eliminating the need for multiple camera and imaging lens setups in machine-vision or identification applications, saving time and expense. The lenses can be used to inspect parts including pharmaceutical vials, batteries, or automotive components. Optimized for use with monochromatic light, these imaging lenses provide a conical shaped working area.
In addition, at 660 nm, when 0.5- to 1.5-mm spacers are positioned between the lens and the camera, TECHSPEC Hypercentric Lenses can also be used as long-working-distance borocopes. The boroscopes can simultaneously focus on the internal walls and bottom surface of an object—a converging view. The boroscope's working distance is the area past the convergence point (CP) of the standard working area. The use of even larger spacers will increase the boroscope's focus distance and allow for easier illumination. TECHSPEC Hypercentric Lenses are available for 1/3-in., 1/2-in., and 2/3-in. sensors.
