Optimizing Halogen Volume in Tungsten Halogen Lamps

Irradiance of Horizontal Quartz-Halogen Standard Lamps

Spectral irradiance calibrations often require that irradiance standard lamps be oriented differently than the normal calibration orientation used at the National Institute of Standards and Technology and at other standards laboratories. For example, in solar measurements the instruments are generally upward viewing, requiring horizontal working standards for minimization of irradiance calibrat...

Halogen transfer through halogen bonds in halogen-bound ammonia homodimers.

Ab initio MP2(full)/aug-cc-pVTZ calculations have been carried out to investigate the halogen transfer between haloamines and ammonia. The results show that the formation of a halogen bond complex between ammonia and the protonated N-haloamine is a preliminary step in the halogen transfer process. The complexation energies, optimized geometries, topology of electron density and potential energy...

Dichroic Halogen Lamps - unsuitable as UV lighting for reptiles

Ordinary incandescent lamps (with a tungsten filament) produce no ultraviolet light. Recently a range of lamps which do emit significant and useful amounts of UV light have become available. Specialist fluorescent tubes, compact fluorescent lamps and mercury vapour lamps, all designed to emit UVA and UVB light in varying amounts, are now on sale worldwide. Over the last year, those of us writin...
