242mm Telecentric Backlight Illuminator

Product Details Optically Collimated Light for Increased Edge Contrast Superior Collimation Ideal for use with Telecentric Lenses Easily Compatible with 8mm Coaxial LEDs or ¼” (0.312”) Fiber Light Guides TECHSPEC Telecentric Backlight Illuminators use the optical design principal of telecentricity to illuminate objects with truly collimated light and produce high contrast, silhouetted images. Standard backlights are diffuse to avoid hot spots, but these diffuse reflections can also reduce edge contrast. TECHSPEC Telecentric Backlight Illuminators have collimated light rays (not diffuse) to increase edge contrast, thereby increasing measurement accuracy. Used in combination with a telecentric imaging lens, these illuminators are ideal for machine vision applications that require accurate measurements and are compatible with 8mm coaxial LEDS or ¼” (0.312″) fiber optic light guides. Note: Additional light source and light source power supply required for operation. Technical Information Why Use Telecentric Illumination?
