BARRINGTON, N.J., Oct. 29, 2012 — Edmund Optics has introduced its TechSpec hypercentric, also called pericentric, lenses. They are suited for inspecting parts and components in machine vision applications.
The lenses provide a converging view of an object, simultaneously focusing on the top and surrounding sides. This eliminates the need for multiple camera and imaging lens setups in machine vision or identification applications, saving time and expense. They are used for inspecting pharmaceutical vials, batteries and automotive parts. Optimized for use with monochromatic light, they provide a conical-shaped working area.
At 660 nm, when 0.5- to 1.5-mm spacers are positioned between the lens and the camera, they also can be used as long-working-distance borescopes that can simultaneously focus on the internal walls and bottom surface of an object.
The borescope’s working distance is the area past the convergence point of the standard working area. The use of even larger spacers will increase the focus distance and allow for easier illumination. The lenses are available for 1/3-, ½- and 2/3-in. sensors.
