SD DUAL   DUAL CHANNEL MINIATURE SPECTROMETER

The SD DUAL spectrograph has two independent spectrographs sharing the same housing. The focal planes of the Spectrographs are matched to provide simultaneous spectrum detection at a 27mm-diode array. The SD DUAL has both high quality optics and proven electronics . The optical system uses a special grating to cheive a dual channel device. Both channel outputs are detected by a highly sensitive CCD detector or low noise photodiode array. Both channels cover the same spectral range and are used in situations where a reference channel is required. 

 

Available in four spectral ranges from UV to NIR.

USB, RS232 or parallel printer port PC interface.

Complete, plug into PC and run. No plugin PC card required.
