Most of the reflected light is directed away from the camera (creating the dark backdrop), and only the light scattered off of any features with edges is collected by the camera, creating a striking contrast. <\/p>\n\n<p>This technique is suited to all materials and is commonly used to highlight surface irregularities, defects, and fine details. The MR-Dark Field is perfect for creating contrast in these applications, even on shiny or reflective surfaces. <\/p>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-layout-1 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"380\" height=\"380\" src=\"https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Code.png\" alt=\"mr dark field code sample\" class=\"wp-image-17947\" srcset=\"https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Code.png 380w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Code-300x300.png 300w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Code-150x150.png 150w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Code-360x360.png 360w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Code-175x175.png 175w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Code-40x40.png 40w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Code-55x55.png 55w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Code-100x100.png 100w\" sizes=\"(max-width: 380px) 100vw, 380px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\">DPM code on black plastic<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"380\" height=\"380\" src=\"https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Coin.png\" alt=\"mr dark field (dkf)\" class=\"wp-image-17950\" srcset=\"https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Coin.png 380w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Coin-300x300.png 300w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Coin-150x150.png 150w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Coin-360x360.png 360w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Coin-175x175.png 175w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Coin-40x40.png 40w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Coin-55x55.png 55w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-Coin-100x100.png 100w\" sizes=\"(max-width: 380px) 100vw, 380px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\">Ridge inspection<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"380\" height=\"380\" src=\"https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-PCB-1.png\" alt=\"mr dark field (dkf)\" class=\"wp-image-17955\" srcset=\"https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-PCB-1.png 380w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-PCB-1-300x300.png 300w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-PCB-1-150x150.png 150w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-PCB-1-360x360.png 360w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-PCB-1-175x175.png 175w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-PCB-1-40x40.png 40w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-PCB-1-55x55.png 55w, https:\/\/www.tpl-vision.com\/wp-content\/uploads\/2024\/06\/DarkField-PCB-1-100x100.png 100w\" sizes=\"(max-width: 380px) 100vw, 380px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\">PCB inspection<\/p>\n<\/div>\n<\/div>\n\n<h2 class=\"wp-block-heading\">COLOUR VARIATIONS<\/h2>\n\n<p><strong>TPL Vision is extremely careful about BIN sorting in the selection of LEDs for their products<\/strong>.<\/p>\n\n<p>Specifically for the Cyan series on this product, the human eye is very sensitive to colour variations.
