멀티채널 스펙트로라디오메타 - SPMC

(MULTI CHANNEL SPECTRORADIOMETER)

The Multichannel Spectrometer SPMC

The multichannel spectrometer SPMC (download datasheet 148kB) allows the parallel reading of up to eight spectra in the VIS (UV) wavelength range.
The measurement is proceeded simultaneously without a time delay between the several channels. Each channel has an own optical input. Therefore there are no moveable parts inside which reduce the reproducibility.
The amplification of each channel can be adjusted seperately by software to adapt the instrument on the specific application. Furthermore the instrument offers a trigger input and a lamp/ shutter output.
ATX is suited for the reading of up to eight spectra as well as transmission/ reflection calculations. Single and continuous measurement modes are possible. Data can be exported to Excelä spread sheets and to ASCII files. The optimal integration time can be found by an automatic setting.

 

The multichannel instrument SPMC can be delivered with two different kinds of spectrometers a low cost version and a version for more demanding applications.
