The SpectraPen SP 110 is a low-cost, handheld spectrophotometer that is ideal as a general-purpose instrument for research labs, agricultural and industrial 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.
The SpectraPen SP 110 is a low-cost, portable spectrophotometer ideal as a general-purpose instrument for industrial and research applications. The SpectraPen is especially useful for quick measurements of solar irradiance and spectral light quality control. The external light source and sample holder allow the SpectraPen to be used also for absorption, reflectance, transmittance, emission, color and fluorescence measurements of various samples.
The rechargeable lithium-ion battery, splash-proof case and integrated GPS module make the SpectraPen an ideal tool for environmental, agricultural and ecological applications, such as monitoring artificial lighting used in the horticulture industry or testing light sources. The spectrum of the measured light source is instantly displayed on the SpectraPen's touchscreen. All recorded data is automatically stored in the device's internal memory. The SpectraPen also includes a comprehensive software package covering full system control, data acquisition and processing.
APPLICATIONS Indoor and outdoor visible light source testing Spectrum measurements of optical filters and protective screens Quality of artificial lighting
SPECTRAPEN MEASUREMENTS
Oscilloscope: approximate spectrum data
Absorbance (external sample holder and light source required) A=log(I0/I), where I0 is the reference light intensity and I is the measured light intensity
Transmittance (external sample holder and light source required) T= I/ I0, where I0 is the reference light intensity and I is the measured light intensity
SOFTWARE Different operating modes: oscilloscope, absorbance, transmittance Different tools: zoom, marker, auto-scale, curve smoothing Automatic integration time setting Data browsing and averaging Data display and transfer routines to Microsoft Excel GPS mapping plug-in
Versions
SpectraPen SP 110-UVIS Wavelength range: 340 to 790 nm.
