  • Is the CI-710s waterproof?

  • The CI-710s is not designed to be waterproof and should not be used underwater. The CI-710s is designed to be water-resistant. Use in light rain is fine, however, there are electronics that can be damaged from water entering the instrument, so it is not recommended to use the CI- 710s during heavy rainfall.

  • Does this product come with a warranty?

  • All CID Instruments come with a 12-month warranty at the point of sale. The warranty covers repairing and replacing defective parts of the instrument that were manufactured directly by CID Bioscience. The warranty does not cover wear and tear, neglect, misuse, accident, or excessive deterioration. Further, unauthorized repair and alteration by an unauthorized party voids the warranty. More information can be found in the operation manual of your instrument.

  • What are the operating conditions for this product?

  • The operating conditions for the CI-710s are –10° to 50° Celsius and 0%-90% noncondensing humidity.

  • What different types of researchers use the CI-710s?

  • Plant physiology, forestry, environmental, and crop researchers all benefit enormously from the metrics that SpectraVue Leaf Spectrometer provides.

Theory of operation

SPECTRAVUE is a powerful spectrometer paired with a leaf probe attachment, on-board operating software, and display screen. Two broadband light sources are attached inside the device. One is positioned in the leaf clamp for transmissive measurements, and one is placed inside the case for reflective measurements. The spectrometer module takes the light from the leaf probe attachment and projects the wavelength dispersed light onto a CCD array. Each pixel of the CCD array thus corresponds to a specific wavelength of light. The operating software displays the light intensity of each pixel of the CCD array.

Three spectroscopic measurements can be performed by SPECTRAVUE:

Transmittance (T) is the fraction of the incident light passing through a sample, such as a leaf. When the intensity of the incident light is Io, and the intensity of light passing through the sample is It, the transmittance, T, is then expressed as T = It / Io. The CI-710s software suite can automatically calculate and plot the transmission spectrum with the reference spectrum (the intensity profile of the light source) stored.

Absorbance (A) is related to the transmittance as A = – log T = -log(It / Io). Absorbance is commonly denoted in optical density (OD) as it is linearly proportional to the amount of light absorbing sample in the light path length (Beer-Lambert law). For example, in a standard 1-cm cuvette, a sample with an OD of 2 is twice as concentrated as a sample with an OD of 1. But note that the intensity of light transmitted from a sample with an OD of 2 is only 1/10 of that from a sample with an OD of 1. 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.

Reflectivity (R) is the fraction of incident light that is reflected from a sample. Depending on the purposes of the study, reflectivity can be measured for reflection at a specific angle from the sample, or the entire reflected hemisphere. The leaf probe attachment of CI-710s is not designed to measure the directional reflectivity. Nonetheless, it can be used to measure the absorption spectrum of surface substance of reflective or opaque samples.

The SpectraVue Leaf Spectrometer is designed to simultaneously measure the transmission, absorbance and reflection of light by biological substances within a wide range of wavelengths that cover visible and near-infrared (NIR) light.
