Telecentric illumination is quickly becoming the illumination of choice for precision metrology due to its ability to produce "hard" edges that can be easily analyzed.
Join Nick Sischka, Vision Solutions Specialist and member of EO's Imaging Team, as he reviews some best practices to consider when designing an imaging system.
Nick Sischka explains why color consideration and illumination are so important for machine vision in this hands-on demonstration from the Edmund Optics 2021 Imaging Innovation Summit.
Fresnel lenses are composed of a series of concentric grooves etched into one side of a sheet of plastic. Fresnel lenses are unlike typical spherical or aspherical optical lenses.
