Spectral Imaging in Astronomical Objects
Astrophotography uses spectral imaging to measure diverse properties of astronomical objects including molecular composition, ionization state, redshift, and temperature.
Chroma Technology manufactures the highest quality, narrow-band spectral line filters for detecting ionized sulfur, oxygen, and H-alpha or H-beta, and other elements. Chroma’s very narrow passbands provide the precision and accuracy needed to ensure your spectral line of interest is transmitted with almost no unwanted wavelengths, thereby enhancing the contrast.
These filters have extremely durable, sputtered, hard coatings, using single substrates of the best glass, therefore eliminating the need for laminations. These coatings can withstand humidity changes and extreme temperature fluxes and remain spectrally accurate in center wavelength (CWL) and bandpass adherence. All primary filter coatings are applied on the front surface and anti-reflection coatings on the rear surface. This prevents ghosting and maximizes transmission.
Chroma’s longtime commitment to providing attentive, knowledgeable customer service and complimentary technical support makes this company the partner of choice for OEMs and astrophotographers who use specific instrumentation.
All filters may be used with apertures of f/4 or smaller. Custom coating services can be provided for more demanding imaging applications that require larger apertures such as f/3 or f/2. Chroma can also provide larger sizes and unique passbands upon request.
