Chroma Technology H-beta filters are 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.

Chroma Technology H-beta filters are available in the following filter sizes:

  • 1.25″ Mounted
  • 2″ Mounted
  • 31mm Unmounted
  • 36mm Unmounted
  • 50mm Unmounted
  • 50x50mm Square Unmounted

Optical Density Data:

27005 - H-beta 5nm Optical Density

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
