Keterangan

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. For example, most photosynthetically active green leaves strongly absorb blue/ blue-green light and reflect red and yellow 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.
