LP850 Near-IR Longpass Filter
Near-IR Longpass Filter for machine-vision imaging — passes 870-1100nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
LP850 filter material is excellent for eliminating overwhelming visible and NIR ambient light, particularly in cases where the spectral response of the camera beyond 900nm is approaching zero. Otherwise we encourage customers to consider using an LP920 filter instead.
