  • LP1580 Longpass Filter - SWIR Spectroscopy & Sorting (Plastic & Chemical Analysis)

    LP1580 Longpass Filter - SWIR Spectroscopy & Sorting (Plastic & Chemical Analysis)

    SWIR Spectroscopy & Sorting (Plastic & Chemical Analysis)

    • Many organic compounds, including lipids and specific plastics (like PVC, PET, and PS), have distinct absorption fingerprints in the 1600–2500 nm range. This filter allows a sensor to focus entirely on these longer wavelengths to distinguish materials in recycling or industrial sorting.

    Recommended Light Sources

    • Tungsten-Halogen Lamps: They emit a continuous, stable broadband spectrum that covers the entire 1600–2500 nm range, which is essential for capturing the complete absorption "fingerprints" needed to distinguish between complex organic materials like PVC, PET, and PS.
    • Supercontinuum Lasers: They provide high-intensity, broadband light with the focus ability of a laser, allowing for rapid signal detection on high-speed industrial conveyor belts where standard lamps might not provide enough photon flux for fast integration times.

    LP1580 Longpass Filter - Telecom & Laser Line Separation

    Telecom & Laser Line Separation

    • L-Band and U-Band Isolation: Standard telecom optical fibers use the C-band (1530–1565 nm). This filter effectively blocks the C-band while passing the L-band (1565–1625 nm) and U-band (1625–1675 nm), making it useful for testing or separating these specific communication channels.

    Recommended Light Sources

    • Tunable Lasers (L-Band/U-Band): These allow for precise wavelength selection across the 1565–1675 nm range, which is critical for characterizing the performance of individual communication channels and verifying that the filter is correctly isolating them from the C-band.
    • Amplified Spontaneous Emission (ASE) Sources: They provide a stable, high-power broadband spectrum specifically covering the L and U bands, making them ideal for measuring the total spectral insertion loss and crosstalk of passive components in a single sweep.
