405nm narrowband bandpass filter High blue light lens customization bandpass optical filter

  • glass optical filter
  • custom optical filter
  • factory offer optical filter
  • 405nm optical filter
  • Precision narrow bandpass interference filter centered at 405 nm (violet-blue boundary), designed to transmit a sharp 405 nm ± 5–10 nm band while blocking UV (<380 nm) and visible/NIR (>420–1100 nm). 

    Hard-coated on UV-grade fused silica or N-BK7 glass via ion-assisted deposition for high environmental stability.

     Available as stand-alone filter windows or integrated onto plano-convex / aspheric lenses (filter-coated lens) for 405 nm LD/LED isolation, fluorescence excitation (DAPI/Hoechst), UV curing monitoring, and high-blue light detection systems.

     Fully customizable for OEM instrument integration.

    Description

    405nm narrowband bandpass filter High blue light lens customization bandpass optical filter

    Applications:
    • 405nm Laser Diode / LED Isolation — Pass only 405 nm emission, suppress UV leak & visible bleed
    • Fluorescence Excitation (DAPI / Hoechst / Alexa Fluor 405) — Narrowband excitation filter for blue-fluorescent dyes
    • UV Curing Process Monitoring — Selective detection of 405 nm UV source intensity
    • Biomedical & Analytical Instruments — Flow cytometry, microplate readers, DNA sequencers
    • Machine Vision UV Inspection — 405 nm bandpass for crack / defect detection under violet illumination
    • High-Blue Light Hazard Measurement — Isolate 405 nm component for safety evaluation
    • Forensic & Document Verification — Banknote / ID card UV feature examination
