IR Cut-off Filter

IR cut-off filter blocks the transmission of infrared light while it allows the transmission of visible light. It is used for the CCD camera to produce true color images and to avoid the color deviation. It keeps the natural and vivid reality when the primary colors are displayed.

	Application : Digital Camera CCD Camera Color Scanner
	Features : High IR energy reflection Excellent Visible transmission
