C11482GA
For near IR, integrating optical system,
image sensor and circuit
Hamamatsu TG series mini-spectrometer C11482GA is a polychromator integrated with optical elements and an image sensor.
Light to be measured is guided into the entrance port of the C11482GA through an optical fiber and the spectrum measured
with the built-in image sensor is output from the USB port to a PC for data acquisition. The C11482GA is a palmtop-size unit
and operates on USB bus power. It comes 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.

*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 1300 nm 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.
