Miniature Leaf Spectrometer (CI-710)

Mã sản phẩm : 1489637520

The CI-710 Miniature Leaf Spectrometer is designed to measure the transmission, absorption, and reflection of light by biological substances within a wide range of wavelengths that cover visible and Near Infra-Red (NIR) light. Transmission and absorption spectrum measurements are the most common applications of spectrometers. The spectrum can be used for the quantification of chemical concentrations, color analysis, the study of photochemical reactions such as photosynthesis, and the quantification of physical or optical properties such as film thickness, index of refraction, and extinction coefficient. A biological system may absorb light efficiently at a certain range of wavelengths and transmit/reflect other wavelengths of light. The presence of different pigments, organic compounds, or inorganic chemicals in biological substances may exhibit distinct characteristics in the wavelength spectrum. These unique spectral characteristics can provide useful information for many physiological studies of biological systems, including monitoring the metabolism involving photosynthesis, status of nutrient uptake by plants, changes in chemical content or concentration in plant organs, biomass changes with respect to the environmental parameters, and detection of plant diseases.

    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.
