532nm Bandpass Filter

High-Performance 532nm Bandpass Filters

Discover our precision-engineered 532nm bandpass filters designed for laser applications, fluorescence microscopy, and optical instrumentation. These filters provide exceptional transmission at the 532nm wavelength while effectively blocking unwanted light.

Key Features:

  • Optimized for 532nm green laser wavelengths
  • High transmission efficiency and sharp cut-off characteristics
  • Superior optical density for background suppression
  • Compatible with microscopy, spectroscopy, and laser systems
  • Available in multiple sizes and mounting options

Perfect for applications including confocal microscopy, flow cytometry, Raman spectroscopy, and laser-based research. Our 532nm filters deliver the optical performance you need for demanding scientific and industrial applications.

  • Raman Spectroscopy (Laser Line Filter)

    • OD > 3
    • FHWM <= 3nm

    Extremely narrow FWHM is needed to pass only the laser line and reject a large portion of the surrounding laser noise. High OD provides deep blocking of unwanted light, but a separate, even higher OD edge or notch filter is used to block the main 532 nm scattered light from the sample.

  • Laser Line Clean-up/OEM Laser Systems

    • FWHM < 5nm
    • OD > 3

    Used directly on a 532 nm laser (often frequency-doubled Nd:YAG) to eliminate spontaneous emission, residual pump light, and harmonics. Narrow FWHM ensures spectral purity, and high OD blocks unwanted out-of-band radiation.
