SpectraPen Z850 is a handheld spectrometer. The SpectraPen is powered by Li-ion rechargeable battery and does not require any PC or other bulky accessories.  Light wavelength and intensity readings of any light source are instantly displayed as spectral traces on the SpectraPen touch screen display.  Optional  fiber optic cable is also available.

** When monochromatic light of Λ = 550 nm or Λ = 850 nm is input, spectral stray light is defined as the ratio of the count measured at the input wavelength, to the count measured at a wavelength 40 nm longer or shorter than the input wavelength.

The new Z800 Spectrometer was developed for high-resolution, fiber optic spectroscopy applications in the UV/VIS to NIR range. It can be used as a stand-alone instrument or as a substantial enhancement of other instruments to analyze spectral composition of irradiance. Ultra-high sensitivity of the instrument allows measuring fluorescence emission spectra of individual cells when combined with Z500 Micro FluorCam. The spectra can be measured in the range from UV (200 nm) to NIR (980 nm) with FWHM bandwidth of 3.5 nm. Fast recording can capture as many as 100 spectra per second with data resolution of 16 bits.
