Fully automatic plasmon surface wave spectroscope designed and fabricated at SBU

Fully automatic plasmon surface wave spectroscopy was designed and built by the Magnetoplasmonics Group of the Laser and Plasma Research Institute of SBU.

Dr. Seyedeh Mehri Hamidi Sangdehi, head of the Magnetoplasmonics Laboratory of the Laser and Plasma Research Institute, announced the above news, adding: "A spectroscopic system of fully automatic plasmonic sensors was designed and built for the first time in the country and with the support of the Photonics, Laser, Advanced Materials and Manufacturing Technologies Development Headquarter. Due to the accuracy of measurement and reproducibility of sensors that are designed based on plasmonic stimulation, this system has been introduced as a replacement for its laboratory equivalent and as an industrial product. In connection with this system, the user only needs to design an optical sensor, and this platform performs the following: the required analyzes in the physical arrangement, which requires adjusting the angles of the light source arms and light reflection arms, spectral sampling at different angles, light spot imaging, data analysis on the spectrum, data storage and data transfer to memory.

Referring to the application of fully automatic plasmonic surface wave spectroscopy, he explained: "Since the optical sensors based on plasmonic surface waves is widely applied in the fields of medical detection, nanotechnology, gas detection, oil industry and research sciences in the field of light physics, this system can also be used in various industrial and research projects.

Dr. Hamidi enumerates the specifications of this system: “Wide-band visible light source, angle accuracy with a resolution of 0.1 to 1 degree, spectral band spectroscopy in the range of 350 to 800 nm, angle broom from 20 to 70 degrees, data analysis on spectral data and extraction of angular sensitivity graphs in terms of wavelength, data analysis on spectral data and extraction of sensogram diagrams, spectrum extraction from radiation to study the phenomenon of focused surface waves, and spectroscopy duration of 3 to 10 minutes.”
