Place of Origin:Jilin China (Mainland)	Brand Name:CNI	Model Number:Aurora4000	Range Broadband:200~1100nm
Resolution:0.75nm FWHM

Aurora4000 spectrometer is developed by Jilin Lasertech Opto-Mechatronics equipment Co., Ltd. With3648 pixels CCD linear array detector, it 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 are as below

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
