Chroma 3nm H-beta Filter

$718.75$1,937.50

  • H-beta filters are also useful for imaging nebulae and objects rich in ionized hydrogen. At 486.1nm, a narrow-band filter is required to separate H-beta from nearby blue and green spectral lines. Although weaker than the H-alpha line, this is often used for visual detection as the longer red wavelengths of H-alpha are difficult to detect by eye
  • Extremely durable coatings withstand humidity changes and extreme temperature fluxes and remain spectrally accurate
    in CWL and band pass adherence
  • No reflections leading to image distortions or “back reflections”
