Optical Filters for the Astronomy Market
Chroma Technology manufactures the highest quality astronomy filters
Astrophotography uses spectral imaging to measure diverse properties of astronomical objects including molecular composition, ionization state, redshift, and temperature.
At Chroma Technology we manufacture the highest quality, narrow-band spectral line filters for detecting ionized sulfur, oxygen, and H-alpha or H-beta and other elements. Our 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.
Our filters have extremely durable, sputtered hard coatings using single substrates of the best glass, 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 to prevent ghosting and to maximize transmission.
Our longtime commitment to providing attentive, knowledgeable customer service and complimentary technical support makes us the partner of choice for OEMs and astrophotographers who use specific instrumentation.
