With 3648 pixels CCD linear array detector, Aurora4000 spectrometer has high resolution up to 0.02 nm (FWHM). The system includes incident slit, collimating mirror, dispersion element (grating), focusing optical system and detector. Light is collected  through the optical fiber into the spectrometer slit then the spectral information can be read out by the software.

Triggering options
Triggering Mode Description Applicable Spectrometer(s)
Normal Spectrometer acquires spectra continuously. GE+TG
External Software Integration time is set in the software. Software receives a trigger event and transmits spectra obtained in the data acquisition cycle in which the trigger occurred. GE+TG
External Hardware Integration time set via chip in spectrometer. Spectrometer waits for a sharp rise in voltage on the trigger input pin, and then acquires spectra until the voltage is removed. TG

External

Synchronization

Spectrometer acquires data from an external trigger event until the next time the trigger is activated, at which time the spectrometer ceases spectral acquisition and begins a new acquisition. Integration time cannot be set, since the trigger can fire at random intervals. TG
