- Infrared Lighting for machine vision is used in many inspections to reduce the color of an object to make other points more visible. Infrared Lighting can also be used to reduce glare and reflections to allow for closer imaging. Due to the longer wavelength Infrared can see through lighter materials of plastic, cloth, paper, and some organic materials to allow for internal inspection. Metaphase Technologies offers Infrared Lighting in many of our products. Infrared Lighting can be used in inspection processes such as building inspection, air leakage, chemical identification, food inspection, and plastic inspection.
