A task group of CCT-WG5 (radiation thermometry) was established in May 2008 to write text for the mise-en-pratique for the definition of the kelvin (MeP-K) for high temperatures. This task group reviewed and gave summaries for the existing techniques

For accurate determinations of thermodynamic temperature, NPL has developed its absolute radiation thermometer (ART), which is calibrated traceably against a cryogenic radiometer. This article reviews some of the potential sources of systematic uncer

Narrow-band filter radiometers at 248?nm, 313?nm, 330?nm and 368?nm wavelengths were used to compare calibration facilities of spectral (irradiance) responsivity at HUT, NPL and BNM?INM. The results are partly in agreement within the stated uncertain

Improving the accuracy of the measurement of ultraviolet (UV) radiation is one of the most challenging problems facing radiometrists today. The difficulties arise in part from the stability and performance of the optical components required to make t

A mode-locked titanium sapphire laser, tuneable over the region from 680 nm to 1000 nm, has been used to generate monochromatic laser radiation over the region from 250 nm to 450 nm by second and third harmonic generation, with power outputs of betwe

The realization of a new detector-based ultraviolet spectral-radiance scale is presented. The paper describes the characterization of an interference filter radiometer centred at 358 nm and its use to determine a point on the spectral-radiance scale

Although the pregnancy hormone hCG has been extensively mapped immunochemically, few monoclonal antibodies have been produced to the unique COOH-terminal region of its beta-subunit (beta CTP). We now report the development and characterization of fiv

Photodiode-array-based spectrometers are increasingly being used in a wide variety of applications. However, the signal measured by this type of instrument often is not what is anticipated by the user and is often subject to contamination from stray

The translational energy dependence of product rotational alignment in kinematically constrained reactions of the type H + H′L → HH′+ L has been analysed in terms of a simple dynamical model, the constant product orbital angular momentum (CPOAM

Harmonic generation of the output of a mode-locked titanium sapphire laser is a highly effective means for producing high power, quasi-cw, wavelength tunable radiation in the 200-500 nm spectral range. The laser is not truly cw, consisting of pulses
