Part of the power of the CI-710 Miniature Leaf Spectrometer is its ability to scan and record across a wide spectrum, from 400-950 nm. Many researchers wish to analyze multiple, discrete peaks or integrate across wavelength bands. These functions are readily accomplished with the SpectraSnap! software that ships with the CI-710.
Other users of the CI-710 have expressed a need to rapidly estimate vegetation properties using published and accepted indices. These indices include: estimates of greenness like the widely-used Normalized Difference Vegetation Index (NDVI); plant stress, such as the Plant Senescence Reflectance Index (PRSI); pigment concentrations, including carotenoids and anthocyanins; and leaf water status estimated by the Water Band Index (WBI).
Now, with SpectraSnap!, these indices and others can be easily and simultaneously measured. SpectraSnap! gives the CI-710 user the power of many single-measurement instruments in one package. Researchers can also add their favorite algorithms to the library.
Why SpectraSnap!
Since its introduction, CID's compact and light-weight CI-710 hardware has simplified the process of collecting spectral signatures from plant tissue. Now SpectraSnap! simplifies data analysis by offering several real time computations in an intuitive and easy-to-operate system.
Save Time
Insert the sample into the CI-710 hardware and the selected calculations are instantly displayed along with raw and averaged spectroscopic data. Press Stop to pause the live stream or Save to record the on-screen measurement. It's that easy.
Ready to use out of the box. Flexible when you need it.
Choose the calculations to display from a convenient selection of popular vegetation indices (NDVI, PRI, CRI, ARI, etc) and/or define your own calculations to target specific areas of interest.
