SP675 Near-IR/Deep Red Dichroic Block Shortpass Filter
Near-IR/Deep Red Dichroic Block Shortpass Filter for machine-vision imaging — passes 355-635nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
SP675 filters excel at providing accurate color rendition for digital cameras. Compared to any other IR cut filters available from various suppliers, SP675 filters are notably more efficient at blocking near IR radiation to a far greater degree. These filters block slightly less red light compared to SP645 filters. Custom fabricated diced or rounded SP645 and SP675 filters can be supplied with short lead times.
