Are you designing a system and debating whether or not to use in-line illumination? Read more about the proper time to use in-line and comparisons at Edmund Optics.
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.
Polarization Overview - Part 2: Waveplates & Retarders (Advanced)
Waveplates and retarders are optical components designed to transmit light while modifying its polarization state without attenuating, deviating, or displacing the beam.
Choosing the right backlight illumination is critical for precise measurement and edge detection in machine vision applications. Learn about your best options!
In order to understand vignetting, it is important to understand sensor sizes, formats, and roll-off and relative illumination. Find out more at Edmund Optics.
