Due to its slim profile of 21mm thickness and narrow 5mm borders, the collimated backlight CSback of TPL vision makes it possible to achieve high-contrast images. The backlight can be used with regular C-mount lenses as well as telecentric lenses, providing uniform illumination at various sizes from 50x50mm to 200x200mm. Key application areas include the imaging of clear parts and objects with rounded edges, which are notoriously hard to inspect with improper lighting due to the lack of contrast. This is a common concern especially for pharmaceutical and food and beverage applications.
