Edmund Optics Inc. has released the telecentric backlight illuminator for machine vision measurement applications. The device uses a telecentric lens and parallel rays to increase edge contrast and accuracy, and it features an adjustable aperture to allow for variable output without varying colour temperature. It accepts 1/4-in. fibre optic lightguides or 0.312-in. LEDs and, according to the company, it provides shorter integration time than typical fibre optic or LED backlights.
