The complex is intended for recording the spectral responses of the UV-visi
ble radiation in various analysis modes (absorption and emission spectropho
tometry, spectrofluorometry, and Raman spectroscopy), as well as scanning m
odes (excitation and luminescence wavelengths, and synchronous one). The op
en architecture of the automation hardware and software allows one to flexi
bly change the complex configuration and operation mode and to expand the r
ange and composition of spectral devices. The amplifier-converter with a lo
w level of input current noise (1.5 fA in a range of 0-1 Hz) provides photo
current recording in the 116-dB dynamic range.
