Signal Processing and Control System:   

Figure “a-2” shows the signal processing and control system 
arrangement.    This system is controllable with the operation 
panel.    After opto-electric conversion by a pair of detectors, 
electric signals are amplified and A/D converted, and then 
logarithmically converted by software to generate absorbance 
data.    The result of measurement is displayed on the data 
display unit and can be printed with the printer.
