Infrared light often transmits through material more than visible light wavelengths. This common feature can be used as a solution to common machine vision inspection that require seeing through surface layers or material.

	A backlight with visible light does not transmit through wafer.	An IR backlight passes through the wafer material to uniformly silhouette the pattern.
	Visible light of any wavelength illuminates the graphics behind the date.	IR light passes through the occluding graphic pigment but not this printed date code enabling reliable OCR/OCV
	Printed text on the cap absorbs visible light causing it to occlude any surface defects or feature detection in the image.	IR light passes through the printed text and reflect uniformly from the unbroken surface allowing for defect or feature detection.
	A visible light from a backlight does not penetrate the plastic bottle.	An IR backlight penetrates the plastic bottle and silhouettes the foreign object resting at the bottom for reliable detection.
