In astronomy, a photometric system is a set of well-defined passbands (or optical filters), with a known sensitivity to incident radiation. The sensitivity usually depends on the optical system, detectors and filters used. For each photometric system a set of primary standard stars is provided. A commonly adopted standardized photometric system is the Johnson-Morgan or UBV photometric system (1953). At present, there are more than 200 photometric sy… In astronomy, a photometric system is a set of well-defined passbands (or optical filters), with a known sensitivity to incident radiation.

SPECTROGON UK WebNov 24, 2016 · Bandpass filters only allow a small range of wavelengths to pass through to the final detector. They are often labeled with two numbers (e.g., 450/50). That means that the filter will detect the wavelengths of the first number within 50 nanometers, or in this case, 425 to 475 nanometers. josh wine ad
