Enabling better global research outcomes in soil, plant & environmental monitoring.


The Miniature Spectrometer MINI-SPEC/MP records spectra of PAR in the visible and far red range.

The MINI-SPEC/MP is, thus, well-suited to study effects of spectral variations of light on photosynthesis. The spectrometer can also be configured to measure sample reflectance which can be used as a proxy for the sample’s spectral absorption properties. Another configuration permits measurements of fluorescence emission spectra of samples where fluorescence excitation occurs either with blue or with green light. A reflectance standard and a special 160 cm cable connecting the MINI-SPEC/MP to the MINI-PAM-II are part of delivery.

Dimensions: Tube of 3.25 cm diameter and 17.5 cm length with flat entrance optics SPEC/P.

Spectral range from 400 to 800 nm.

Spectral resolution between 8 and 10 nm.

Signal saturation at sun light of 4000 μmol m-2 s-1.

Built in blue (452 nm) and green (525 nm) LEDs for fluorescence excitation as well as a tungsten lamp for reflectance spectra.
