*1: Relative sensitivity to the center is within the 10 % range.
*2: Can be added by using options. (A calibration wavelength other than the standard specification can be
selected by using the calibration wavelength selection function.)
*3: Only when Option+20 is specified
*4: The warranty does not include cut cables and/or damaged or degraded elements caused by continuous con-
necting and disconnecting to the sensor section.
