  • H-beta 3 nm Bandpass Filter.
  • 50 mm Square, unmounted.
  • Useful for imaging nebulae and objects which are rich in ionized hydrogen.
  • At the 486.1 nm emission line.
  • Required to separate H-beta from the nearby blue and green spectral lines.
  • Weaker than the H-alpha line, this is often used for visual detection as the longer red wavelength of H-alpha are difficult to detect by eye.
  • Type AS filter.

Product Details

  • This Chroma H-beta 3 nm Bandpass Filter - 50 mm Square:

    is useful for imaging nebulae and objects which are rich in ionized hydrogen. At the 486.1 nm emission line, a narrow-band filter is required to separate H-beta from the nearby blue and green spectral lines. Though it is weaker than the H-alpha line, this is often used for visual detection as the longer red wavelength of H-alpha are difficult to detect by eye.

    Type AS filter.

    Optical Density Values:

    All transmission and blocking (OD) data are actual, measured spectra of representative production lots. Spectra varies slightly from lot to lot. Optical density values in excess of 6 may appear noisy because such evaluations push the resolution limit of low light level measurements.
