LP1070 is a 0.7mm thick silicon Longpass filter with antireflection coatings on both sides optimized for 1100-2300nm transmission. Because silicon is inherently opaque, blocking in the visible and very near-IR spectrums is excellent, and the positioning of the cut-on slope is completely insensitive to the angle of incidence of light impinging on the surfaces. LP1070 also reduces Nd:YAG (1064nm) light transmission by approximately 50%. This filter is mainly intended for use with SWIR camera systems and blocks essentially all light that CCD/CMOS cameras might normally be sensitive to.
