ESCRIPTION
SpectraPen SP 110 is a handheld portable spectroradiometer that is ideal as a general-purpose instrument for research and for
agricultural applications. SpectraPen is especially useful for rapid measurements of solar irradiance and monitoring of spectral light
quality. External light source and sample holder enable to use SpectraPen also for measurements of absorption, reflectance,
transmittance, emission, color and fluorescence of various samples.
Li-Ion rechargeable battery, splash-proof case and integrated GPS module make SpectraPen an ideal tool for environmental, agricultural
and ecological applications such as monitoring of artificial lighting used in horticulture industry or light source testing. Spectrum of
measured light source is instantly displayed on the SpectraPen touch screen. All recorded data are automatically stored into the device
internal memory. The SpectraPen also includes a comprehensive software package comprising full system control, data acquisition and
data processing.
SpectraPen measures:
Scope – rough light spectrum
Transmittance – calculated using the following formula
T= I/I
0
Where: I
0
is reference light intensity
I is measured light intensity
Absorbance – calculated using the following formula
A=log (I
0
/I)
Where: I
0
is reference light intensity
I is measured light intensity
