  • Optical Glass
  • PVD/IAD coating for durability and resistance to scratching, as well as stability on CWL (central wavelength). No deviation from temperature change.
  • Constant stringent quality testing processes - Each filter is tested by spectrophotometer and laser interferometer testing spectrum and wavefront to ensure each filter is a high-quality product

وصف

The wavelength of Hydrogen-beta (Hβ) is 486.1 nm, and the wavelengths of Oiii are 495.9 nm and 500.7 nm. To achieve high transmittance for these two elements, the bandwidth of the channel must cover the wavelength difference between them. Considering that Oiii has a dual-peak bandwidth, the channel bandwidth is set to a wider 30 nm.
