Bi750 Near-IR Interference Bandpass Filter
Near-IR Interference Bandpass Filter for machine-vision imaging — passes 740-765nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
750 nm IR illumination can be used to highlight dyes used in labeling, packaging and manufacturing. These markings often do not stand out when viewed under visible, white or colored light. Use of a Bi750 placed filter over the camera sensor or camera’s objective lens can eliminate interfering visible and longer wave near-IR light in order to greatly improve contrast/detection.
