Devise for detection and analysis of fluorescent infrared marks in biological tissues
Purpose
The device is designed for detection and identification of infrared fluorescent marks in biological
tissues in vivo or in vitro.
Characteristics
The identification device is designed in the form of a tabletop instrument. A semiconductor laser with
a wavelength of 680 nm serves as the source of excitation radiation. The registration system is
based on TOSHIBA 3648-channel charge-coupled device and used to register the distribution of light
intesity on the outlet of a small-sized polychromator and transfer the data to a PC. All systems of the
device are realized in single body. The light-guide is intended for the transfer of the light-signal to the polychomator inlet and admission to the exciting radiation sample from the built-in radiating source. The identification device managing is exercised via USB of a PC.
