  • LP1600 Longpass Filter - 1550 nm Laser Blocking (Raman/Fluorescence)

    LP1600 Longpass Filter - 1550 nm Laser Blocking (Raman/Fluorescence)

    1550 nm Laser Blocking (Raman/Fluorescence):

    • The OD4 blocking at 1580 nm is the critical spec here. It is sufficient to block powerful signals from standard 1550 nm lasers (common in telecom and LiDAR) while allowing detection of Stokes-shifted Raman scattering or fluorescence signals that appear at wavelengths longer than 1620 nm.

    Recommend Light Sources

    • 1550 nm Excitation Laser: To utilize an LP1600 filter effectively in this context, you should use a 1550 nm Narrow-Linewidth Laser.

    LP1600 Longpass Filter - Semiconductor Inspection (Silicon Transparency)

    Semiconductor Inspection (Silicon Transparency)

    • Silicon becomes transparent at wavelengths longer than ~1100 nm. While an LP1100 is standard for this, an LP1600 might be used for specialized defect detection or to eliminate "shorter" SWIR noise (1100–1500 nm) from specific sub-surface features in wafers or ingots.

    Recommend Light Sources

    • Tungsten-Halogen Lamp (Broadband)
    • High-Power SWIR LEDs (Narrowband)
