SpectraPen LM 500

PSI

SpectraPen LM 500 is a handheld spectroradiometer that is pre-configured and pre-calibrated to measure spectral characteristics and to calculate key parameters like Lux, Lumen, PAR and Watt values. LM 500 is especially useful for rapid measurements of light intensity and of spectral light quality in the lab, greenhouse or field. It is also well-suited for wide scope of environmental, agricultural and ecological applications such as monitoring of artificial lighting used in horticulture industry or light source testing.

SpectraPen LM 500 is a complete system with integrated touch screen display and cosine corrector; it is powered by a Li-Ion rechargeable battery. Measured data - light spectrum, intensity readings in user defined range, CIE chromacity diagram, correlated color temperature and many more parameters - are instantly displayed on the SpectraPen display and all recorded data are automatically stored into the device internal memory. Comprehensive software package and USB connectivity provide full system control, data acquisition and easy data post-processing in a PC. LM 500 comes with a handy carrying case.

SpectraPen LM 500 is available in two versions that differ in spectral range: 
LM 500-UVIS: spectral response range 340 to 780 nm 
LM 500-NIR: spectral response range 640 to 1050 nm

and two versions that differ in the position of the cosine corrector: 
LM 500-H: cosine corrector facing up (for limited space measurements) 
LM 500-V: cosine corrector facing front (for field measurements and tripod mount)
