Products Description
NIR Longpass Filter 850-1100nm | 45° AOI, Visible Blocking
The OPTOStokes 45° AOI NIR Longpass Filter is engineered to efficiently block visible light while providing high transmission across the near-infrared spectrum. Designed for 45-degree angle of incidence optics, this high-precision optical filter eliminates stray visible radiation (350–780nm) to improve signal-to-noise ratios in electro-optical sensing and machine vision applications.
