BP550 Near-IR/UV-Block Visible Bandpass Filter

Near-IR/UV-Block Visible Bandpass Filter for machine-vision imaging — passes 405-690nm and blocks out-of-band light for repeatable contrast on the line.

Overview [ 01 ]

BP550 filters effectively pass all visible light and block all light outside the visible range without "discoloring" the image. This single substrate, hard-coated filter is designed for use in full color, white light applications where either IR or UV light (or both) may be present. • Made using a low expansion glass substrate to withstand high temperatures

• Normal thickness is 2mm, but can also be supplied in 1mm thickness and a variety of custom, unmounted size and substrate options, particularly for over-the-camera-sensor applications
