LED-Based Collimating Line-Light Combining Freeform and Fresnel Optics

LED-Based Collimating Line-Light Combining Freeform and Fresnel Optics

Illumination for line-scan machine vision systems is required to produce a highly asymmetric elliptical beam pattern, to maximize system speed and accuracy. The use of LED emitters with symmetric Lambertian emission patterns is challenging in this context, requiring significant beam reshaping. A des...
