The spectrometer is designed mainly for femtosecond lasers in pump-probe systems. However, the device could be also used as a regular NIR spectrometer.
It is based on a single concave diffraction grating, so no other surfaces will disturb the signal. The detector used is an InGaS G9203-256S sensor from Hamamatsu. It contains a TE component for cooling and temperature stabilization.
Acquisition of a spectrum can be triggered internally or by an external TTL signal.
Integration time for a single spectrum can be as short as several microseconds.
