Accurate leaf reflectance measurements have never been easier

Making leaf level reflectance measurements has never been easier, even on tiny samples like individual conifer needles

UniSpec-SC Spectral Analysis System

Laboratory results from a field portable instrument

The UniSpec-SC, commonly referred to as a “Reflectometer”, is a single channel, field portable instrument designed for measurement of leaf/canopy reflectance. It features an innovative user interface with integral computer and large, full color LCD, built-in light source and extensive range of accessories for measurement on individual leaves (including needles) and vegetation. It is a truly, self-contained system that does not require an external PC for operation.  In addition to revealing dynamic features related to the physiological condition of vegetation, spectral reflectance can also be used to derive basic information about leaf or canopy structure, nutritional status and pigment content. Leaf chlorophyll content and nitrogen status are both indicators of integrated leaf physiology. As “health” and photosynthetic performance decline with stress or age, tissue nitrogen and chlorophyll content also decline. Both chlorophyll and nitrogen content can be readily estimated from emperically calibrated estimates of leaf reflectance.

Unlike other remote sensing instruments, the UniSpec-SC features an innovative, ergonomic system console designed specifically for demanding field applications. It has a built-in user interface including integral computer, large, full color graphical LCD, keyboard and touchpad for user inputs, RS232 and USB serial ports and PCMCIA slot.  NO LAPTOP COMPUTER IS REQUIRED.

The UniSpec-SC is supplied complete with a powerful, yet user friendly, software package that runs under the Windows CE.NET operating system. System setup and programming is very simple. In addition to measuring, viewing and storing data, the user has all the facilities required for comparing stored records and calculation of common vegetation indices such as NDVI, mNDVI, PRI, WBI, Summed Green Reflectance and Red/Green Ratio.
