The spectrometer is designed mainly for femtosecond lasers in pump-probe systems. However, the device could be also used as a regular UV-VIS-NIR spectrometer. It is based on a single concave diffraction grating, so no other surfaces will disturb the signal. The detector used is a CMOS S10453-1024Q sensor from Hamamatsu. 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.
Here are the most important features of the spectrometer
