Backlight features telecentric lens design.

Press Release Summary:




Using parallel rays, Telecentric Backlight Illuminator eliminates parallax errors, making it suitable for machine vision applications that need to measure edges. Silhouetting object provides high contrast for optimal edge detection while minimizing unneeded surface detail. Compatible with Silver Series Telecentric measuring lenses, illuminator accepts ¼ in. fiber optic light guides or 0.312 in. LEDs.

Edmund Optics® Backlight Advances Machine Measurement



September 26, 2008, Barrington, NJ. The Telecentric Backlight Illuminator combines the advantages of backlighting an object with the benefits of a telecentric lens design. Backlighting is an excellent way to improve machine vision applications that need to measure edges, because silhouetting the object provides high contrast for improved edge detection while reducing unneeded surface detail. Normal backlights, however, can reduce the sharpness of the edge, because diffuse reflections occur from the broad area output and thus reduce the accuracy of gauging and inspection systems. Because the Telecentric Backlight Illuminator uses parallel rays, it avoids these problems.

Edmund Optics' Telecentric Backlight Illuminator is based on the same principals as telecentric measuring lenses, which improve gauging accuracy by eliminating parallax errors. The Illuminators are compatible with EO's Silver Series Telecentric measuring lenses, which are considered among the best telecentric lenses in the industry. Product Line Engineer Bruce Butkus explains, "This backlit illuminator combined with a telecentric lens provides a powerful combination for a wide variety of machine vision applications."

This device also substantially increases illumination compared to a standard backlight, which allows faster measurements. It accepts 1/4" fiber optic light guides or 0.312" LEDs.

Visitors to Opto Paris (Booth 1.G.30) and Vision Stuttgart (Hall 4, Booth A51) can view EO's Telecentric Illumination Demonstration.
