miniature optical unit on the basis of the spectral range of 1000 to 5000 nm leds

摘要

the present invention generally relates to devices for measuring the concentration of gases in an analyzed environment and, in particular, to the miniature optical cells for the chemical sensor.device for measuring gas concentrations proposed in an analyzed environment containing the corpus, which contains at least one led u0438u0437u043bu0443u0447u0430u0442u0435u043b b, a photodiode, an electronic unit, a potential of at least one u0441u0432u0435u0442u043eu0434u0438u043eu0434u043du044bu043c lighter fluid, as the preamp diode, together with electronic unit, and flat mirrorsthe shell has openings for receipt in an analyzed environment, at least one led emitter has the possibility of creating u0438u0437u043bu0443u0447u0435u043du0438 i'm in the spectral range of 1000 to 5000 nm, photodiode a spectral agreed upon at least one u0441u0432u0435u0442u043eu0434u0438u043eu0434u043du044bu043c lighter fluid.a flat mirrors are available, with the possibility of multiple change the direction of radiation from the at least one u0441u0432u0435u0442u043eu0434u0438u043eu0434u043du043eu0433u043e radiator and sending it photodiode and at least one led emitter is installed in the housing with the possibility of changing its status to adjust the length of the path of the radiation t of at least one u0441u0432u0435u0442u043eu0434u0438u043eu0434u043du043eu0433u043e radiator to the diode.
