The Light Output and the Detection Efficiency of the Liquid Scintillator EJ-309
Applied Radiation and Isotopes, 2014 The light output response and the neutron and gamma-ray detection efficiency are determined for liquid scintillator EJ-309. The light output function is compared to those of previous studies.

Absolute light output of scintillators
IEEE Transactions on Nuclear Science, 1997The absolute light outputs of BGO, CsI(Tl) and some new Ce-doped crystals have been measured to an accuracy of about /spl plusmn/5% using calibrated XP2020Q photomultipliers and standard S3590.03 and S2740.03 photodiodes. The use of small crystals, 9 mm in diameter and 1 mm thick, reduces the corrections for imperfections in the light collection ...

The light output of a mechanical lamp
Journal of Physics E: Scientific Instruments, 1975Light is emitted when relative motion of mercury and a glass occurs. In order to determine the factors affecting the light output and the feasibility of its use as a light source, an experimental device providing for the relative motion of contiguous surfaces of various metals and borosilicate glass was used.

Electrical Engineering, 1940
In illumination problems, it is often necessary to compute the solid angle of a light beam in steradians in order to determine the total flux emitted by the source in lumens. When the plane angle of divergence of the beam is small and, hence, the half angle is small, the use of the common relationship ω = 2π(1 – cos α) becomes quite cumbersome.

How to improve light curing output
The Journal of Prosthetic Dentistry, 1993There are several reasons for low intraoral curing light output as reported in the CRA Newsletter February 1989.l TRCINSFORNER STEPUP Output 126 VAC Fig. 1 illustrates the variation in light output versus line voltage input. The equipment used was a Cure Rite radiometer (EFOS, Williamsville, N. Y.), a Fluke 8921A True RMS voltmeter (John Fluke Mfg. Co.,

A Light Amplifier with High Light Output
1969Publisher Summary This chapter provides an overview of a light amplifier with high light output. Any large-scale projection of a picture signal requires the modulation of an intense light flux. Several methods involve a high-power standard light source that is modulated either by absorption as in the Sciatron or by diffraction as in the Eidophor.

Comparison of the Light Output of Image Intensifier Tubes
Radiology, 1961Image intensifiers are now beyond the realm of experimentation and have become an integral part of the routine equipment in diagnostic radiology. Since the day of W. E. Chamberlain's Carman Lecture, “Fluoroscopes and Fluoroscopy” (1), the need for raising image brightness to cone vision level has been generally recognized.

Light Output Measurement of Solid State Lighting Technology
2019 4th International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT), 2019Records from experiments performed with Solid State Lighting technology are presented and discussed. They were done to expand the local knowledge about light output depreciation from Inorganic Light Emitting Diodes technology. Data were collected at the Campus of the University of Sao Paulo for road lighting and for interior lighting at the Institute ...

Characterizing the output settings of dental curing lights
Journal of Dentistry, 2016For improved inter-study reproducibility and ultimately improved patient care, researchers and dentists need to know what electromagnetic radiation (light) is emitted from the light-curing unit (LCU) they are using and what is received by the resin.

Replication NAND gate with light as input and output
Chem. Commun., 2011Logic operations can highlight information transfer within complex molecular networks. We describe here the design of a peptide-based replication system that can be detected by following its fluorescence quenching. This process is used to negate the signal of light-activated replication, and thus to prepare the first replication NAND gate.
