Low-pressure gas-discharge lamp with improved radiation yield

摘要

The invention relates to a construction of a low-pressure gas-discharge lamp with improved characteristics. An integrated reflector arrangement ensures high radiation yield, a low beam cross-section, a parallel light exit, a longitudinal beam profile and the avoidance of chromatic errors. To improve the precision, a representative reference beam having 10% of the intensity of the main beam is put out which is likewise of high optical quality. The application areas of the construction according to the invention are as follows: Optical analytical measuring devices, in particular UV/visual spectrophotometers, UV/visual detectors in high-pressure liquid chromatography, reflectance measuring devices, circular-dichrometer measuring devices and measuring devices for optical rotary dispersion, UV irradiation devices.
