멀티채널 스펙트로메타 - SPECTRA TWIN

(MULTI-CHANNEL SPECTROMETER)

 

Multichannel spectrometer - SPECTRA twin

spec twin softwareSPECTRA twin (download datasheet 203kB) allows the simultaneous reading of two spectra in the VIS (UV) wavelength range.
The measurement is proceeded without time delay between the two channels, furthermore the reproducibility is high because the lack of movable parts. The software Spec Twin is suited for the read out of the two seperate spectrometers as well as transmission/ reflection calculations. Single and continuous measurement modes are possible.
Data can be exported to Excel
ä spread sheets and to ASCII files.

SPECTRA twin can be delivered with two different spectrometers.
SPECTRA twin can be connected to the PC via USB or RS232 interface.
