Edmund Optics Backlight Advances Machine Measurement

The Telecentric Backlight Illuminator combines the advantages of backlighting an object with the benefits of a telecentric lens design. Using parallel rays, the 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. 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.
