SpectraPen Z850 is a handheld spectrometer with a touch screen display, powered by Li-ion re-chargeable battery and does not require PC to operate.  Light spectrum of any light source is instantly displayed as spectral traces on the SpectraPen touch screen display.  Optional  fiber optic cable is also available for the standard model.  The Z850-LM model contains a light meter (a cosine corrector) so light spectrum measurements are combined with light intensity measurements (PAR).

The SpectraPen is available in one of the two versions: Z850 standard or Z850-LM.  These two versions are available in either UV/VIS – measures in 340 to 780 nm range OR  NIR – measures in 640 to 1050 nm range.  The Z850-LM version is also available with the cosine corrector positioned in the horizontal (H) – facing up orientation or Vertical (V) facing forward orientation. Both Z850 and Z850-LM come with integrated GPS module.
