  • LP520 Longpass Filter - Fluorescence Microscopy & Imaging

    LP520 Longpass Filter - Fluorescence Microscopy & Imaging

    Fluorescence Microscopy & Imaging

    The most common and "perfect fit" application for this filter is as an Emission Filter for green fluorophores.

    • Target Fluorophores: Green Fluorescent Protein (GFP), FITC (Fluorescein isothiocyanate), Alexa Fluor 488, and Cy2.

    Recommended Light Sources

    • High-Power Blue LEDs (470 nm or 490 nm):

    Why recommended: These are the modern standard for widefield microscopy. They are stable, instant-on/off, and emit a narrow spectrum of blue light that sits perfectly within the blocking range of your LP520 filter (OD6 blocking).

    • 488 nm Solid-State or Argon Lasers:

    Why recommended: Used primarily in confocal microscopy or flow cytometry. They provide coherent, intense light exactly at the excitation peak of GFP.

    • Mercury or Metal Halide Arc Lamps (with Excitation Filter):

    Why recommended: These are traditional broadband "white light" sources. To use them, you must place a Blue Bandpass Excitation Filter (e.g., 470/40 nm) in front of the lamp to discard all wavelengths except the blue light needed for excitation.

  • LP520 Longpass Filter - Raman Spectroscopy

    LP520 Longpass Filter - Raman Spectroscopy

    Raman Spectroscopy

    Used to block the Rayleigh scattering from blue excitation lasers (e.g., 488 nm) while allowing the Stokes-shifted Raman signal (which appears at longer wavelengths) to pass.

    Recommended Light Sources

    • 488 nm Blue Laser

    For the Raman Spectroscopy setup you described (blocking Rayleigh scattering while passing Stokes-shifted signals), the recommended light source is a 488 nm Blue Laser.

    • 488 nm CW Laser

    Unlike fluorescence microscopy which can use LEDs, Raman spectroscopy requires a Laser (Light Amplification by Stimulated Emission of Radiation).
