A Luminescence Signal Detector for Oncofluorometry of the Near Infrared Region
A portable high-sensitivity device for recording weak luminescence signals in the near infrared (NIR) region (900–1100 nm) has been developed for applications in laser oncofluorometry. The device consists of a housing with optical lenses, interference filters, and a high-sensitivity NIR photodiode m...

description | A portable high-sensitivity device for recording weak luminescence signals in the near infrared (NIR) region (900–1100 nm) has been developed for applications in laser oncofluorometry. The device consists of a housing with optical lenses, interference filters, and a high-sensitivity NIR photodiode module with a preamplifier, protection circuit, and power supply. It is shown that the use of interference filters of the SL 930–1100 type can significantly increase the efficiency of the device. The use of a photodiode module unit with a sensitivity peak near 960 nm, which maximally coincides with the luminescence peak of ytterbium porphyrin complexes, ensures the sensitivity of detecting weak luminescence signals at the level of several fW. |
