Flux calibration of the Herschel -SPIRE photometer
We describe the procedure used to flux calibrate the three-band submillimetre photometer in the Spectral and Photometric Imaging Receiver instrument on the Herschel Space Observatory. This includes the equations describing the calibration scheme, a justification for using Neptune as the primary calibration source, a description of the observations and data processing procedures used to derive f...
متن کاملEvaluation of calibration methods of a photometer measuring maritime light-emitting diode buoy lanterns
Erkki Ikonen Helsinki University of Technology Metrology Research Institute P.O. Box 3000 FIN-02015 HUT Finland Abstract. A photometer used for on-line product testing of light-emitting diode (LED) buoy lanterns is calibrated for illuminance responsivity using two different methods. The first method is based on absolute calibration of the photometer with the CIE standard illuminant A light sour...
متن کاملThe Effect of Adenosinetriphosphate upon Actomyosin Solutions, Studied with a Recording Dual Beam Light-scattering Photometer
A recording dual beam light-scattering photometer is described which permits kinetic studies involving changes in turbidity, and which is not, as are single photocell instruments, affected by the errors due to the attenuation of the scattered light within the turbid medium. With this method, a renewed study has been made of the physical changes occuring in actomyosin under the influence of ATP.
متن کاملEntrapment–D-(+)-Glucose Water Nanodroplet: Synthesis and Dynamic Light Scattering
In the present research, the D-(+)-Glucose–confined water nanodroplets with mean size in the range of 6-11 nm were synthesized at D-(+)-Glucose different concentrations by AOT reverse micelles (RMs) method as a function of mass fraction of droplet (MFD) at the constant water-to-surfactant molar ratio ( W=40). The dynamic light scattering of the nano-sized water droplets containing the D-(+)-Glu...
متن کاملDesign, construction and calibration of single channel sun-photometer for study of aerosols
Aerosols are tiny liquid or solid particles suspended in the air have a strong influence on air quality, human health and climate change. Sun-photometer is a tool for measuring the optical and physical characteristics of aerosols by using sunlight at various wavelengths from the Earth surface. In this paper, the design, construction, and calibration of a single channel sun-photometer is present...
