850nm narrow band filter optical filters

  • glass optical filter
  • custom optical filter
  • factory offer optical filter
  • 850nm optical filter
  • Precision narrow bandpass interference filter centered at 850 nm (near-infrared), designed to transmit a sharp 850 nm ± 5–25 nm band while blocking visible light (400–800 nm) and out-of-band NIR (860–1100 nm). 

    Hard-coated via ion-assisted deposition on optical glass (K9/BK7 or fused silica) with multi-cavity Fabry-Perot design for steep edges and deep blocking.

     Ideal for IR LED/LD isolation, night vision surveillance, iris/facial recognition, machine vision NIR illumination, and biomedical oximetry sensors. 

    Available as stand-alone filter windows or integrated onto plano-convex / aspheric lenses.

    Description

    850nm narrow band filter circular infrared filter optical filters

    Applications:
    • Night Vision Surveillance Cameras — Pass 850 nm IR illumination, block visible light for covert monitoring
    • Iris / Facial Recognition Systems — Isolate 850 nm NIR illumination for biometric capture
    • Machine Vision & Industrial Inspection — NIR channel extraction for object detection, measurement, and flaw detection
    • Biomedical Oximetry & Pulse Oximeters — 850 nm reference channel for blood oxygen saturation measurement
    • Fluorescence Imaging (NIR Dyes) — Emission filter for Cy5.5 / Alexa Fluor 790 / IRDye 800
    • LiDAR / Time-of-Flight Sensors — 850 nm bandpass for ambient light rejection in ToF cameras
    • Scientific & Analytical Instruments — NIR spectrophotometry, gas analysis, and environmental sensing
