Stellar Photometry with the Optical Monitors [PDF]

International Astronomical Union Colloquium, 1993
AbstractThe Optical Monitors are small optical telescopes which will fly on board of the X-ray satellites SPECTRUM-X-GAMMA (JET-X experiment) and XMM. Their main scientific applications are the simultaneous observations (imaging) in the optical and UV band of the optical counterparts of X-ray sources, with limiting magnitudes of aboutmv=22(JET-X) and ...

Rationale for the Choice of the Ellipsoidal Reflector Parameters for Biomedical Photometers

Приборы и методы измерений, 2021
Biomedical photometersʼ information-measuring systems with ellipsoidal reflectors have acceptable results in determining of biological tissues optical properties in the visible and near-infrared spectral range. These photometers make it possible to study

The photometry of optical instruments [PDF]

Transactions of the Optical Society, 1922
The use of a portable surface-brightness photometer of the polarisation type for the measurement of the fraction of the incident light transmitted by an optical instrument or reflected by a mirror or system of mirrors, and for the measurement of the relative brightness of different parts of the field of view of an optical instrument, is described.
