For near IR, integrating optical system,
image sensor and circuit
Hamamatsu TG series mini-spectrometers C9913GC, C9914GB are polychromators integrated with optical elements and an im-
age sensor. Light to be measured is guided into the entrance port of TG series through an optical fiber and the spectrum mea-
sured with the built-in image sensor is output from the USB port to a PC for data acquisition. The C9913GC and C9914GB allow
accurate measurement with low noise by cooling the image sensor. The C9913GC and C9914GB come supplied with evaluation
software that allows setting measurement conditions, acquiring and saving data, and displaying graphs. Original measurement
software can be designed on an end-user’s side as DLL’s function specification is disclosed.

Water content measurement
Component analysis in food, agriculture fields, etc.
Process control for chemical products
*1: A conversion factor for converting the image sensor pixel number into a wavelength is recorded in the module. A calculation factor
for converting the A/D converted count into the input light level is not provided.

*2: Depends on the slit opening. Values were measured with the slit listed in the table “ Structure”.
*3: Measured under constant light input conditions
*4: When monochromatic light of the following wavelengths is input, spectral stray light is defined as the ratio of the count
measured at the input wavelength, to the count measured in a region of the input wavelength ±40 nm.
