  • Page 92 [Explanation of Optical System] Light emitted by the light source (WI or D2) is reflected by the light source switch mirror (M1) to pass through the entrance slit (S1) and enter the spectrometer. The light source switch mirror (M1) rotates automatically in response to the set wavelength of the light source.

  • Page 96 Fig. 9-5 shows the UV-1700 function block diagram. The CPU controls many of the operations such as light source light up, light source switching, wavelength drive, filter switching, key input, LCD screen displays, printout and communications via the RS-232C I/F. The sample and reference beams enter the detector (Si photodiode) and converted into signal voltage by the preamplifier.
