Keywords: surface plasmon resonance, determination of the SPR angle, SPR in the IR region.

Results of computer modeling of an angular spectrum superficial plasmon resonance in metal films measurements with device PLAZMON-5 with infra-red radiator are analysed. It is shown that use of an infra-red source of radiation allows to improve sensitivity of sensor device in comparison with source of visible light. On an example of dielectric refraction indexes measurement with PLAZMON-5 device experimental check of theoretical calculations has been carried out.
