SpectraPen SP 100

SpectraPen SP 100 is a handheld spectrometer that's ideal as a general-purpose instrument for research labs, agricultural and industrial applications. SP 100 is especially useful for rapid measurements of solar irradiance and monitoring of spectral light quality.

SP 100 works with Li-Ion rechargeable battery and does not require any PC or any other bulky accessory. Instead, wavelength and intensity readings and their spectral lines are instantly displayed on the SpectraPen touch screen display. All recorded data are automatically stored into the device internal memory. The SpectraPen also includes an integrated GPS module and comprehensive software package including full system control, data acquisition and data processing.

SpectraPen SP 100 is available in two models:
- SpectraPen SP 100-UVIS with wavelength range 340 to 780 nm
- SpectraPen SP 100-NIR with wavelength range 640 to 1050 nm.

See also the enhanced device version SpectraPen LM 500 with calibrations for key irradiance units, like Lux, Lumen, PAR, Watt, etc., as well as Poly-PlantPen RP 400 comprising complete setup for measuring leaf reflectance parameters.
