WebPossible Variation in Methane Quad Filter Transmission . Polarimetry. WFPC2 has a polarizer filter which can be used for wide-field polarimetric imaging from about 200 through 700 nm. This filter is a quad, meaning that it consists of four panes, each with the polarization angle oriented in a different direction, in steps of 45 o. The panes are ... WebA photometric system defines a set of optical bandpass filters for use in observations, which can be calibrated against a number of primary standard stars to ensure recordings are comparable across different observations. The system may be defined using a combination of letters agreed by astrophysicists around the world, including for example:

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.

These are optical instruments for measurement of the absorption of light of a given wavelength (or a given range of wavelengths) of coloured substances in solution. From the light absorption, Beer's law makes it possible to calculate the concentration of the coloured substance in the solution. Due to its wide range of application and its reliability and robustness, the photometer has become one of the principal instruments in biochemistry and analytical chemistry.
