About...

The SpectraPen LM 510 is a handheld portable spectroradiometer that is ideal as a multi-purpose instrument for research, industrial and agricultural applications.

The SpectraPen LM 510 is available in two versions calibrated for either visible light in range of 380 – 780 nm or for VIS-NIR light in range of 640 – 1,050 nm. It measures irradiance in radiometric or photometric units.

The SpectraPen is ideal for rapid measurements of spectral quality and photon flux when monitoring natural or artifcial lighting.

SpectraPen LM 510

SpectraPen LM 510 is a handheld portable spectroradiometer that is ideal as a general-purpose instrument for research and for agricultural applications. SpectraPen LM 510 measures in radiometric or photometric units the intensity of the light received and is calibrated for visible light in range of 380 – 780 nm and the light in range of 640 – 1,050 nm. SpectraPen is especially useful for rapid measurements of spectral light quality, for monitoring of artifcial lighting and for quantifcation of light radiation.

The SpectraPen works with Li-Ion rechargeable battery and does not require for operation any PC or any other bulky accessory. On the SpectraPen touch screen the wavelength and intensity readings and their spectral lines including correlated color temperature index are instantly displayed. All recorded data are automatically stored into the device internal memory. The SpectraPen includes a comprehensive software package comprising full system control, data acquisition and data processing. The SpectraPen is suited for wide scope of environmental, agricultural and ecological applications such as monitoring of artifcial lighting used in horticulture industry or light source testing.
