Suggested application: Leaf Reflectance
Dracaena deremensis leaf reflectance was measured using aSPECTRAL EVOLUTION PSP-1100 Spectrophotometer with
optional fiber optic cable and leaf clip attachment. The graphs
were generated using the easy-to-use DARWin SP Data Acquisition and Analysis software included with each PSP-1100. Redand green traces represent scans from two different regions ofthe same variegated leaf. DARWIN SP allows users to plot multiple scans on the same graph for easy comparison and analysis. All units feature automatic exposure control and autoshutter for simple operation.

Suggested application– Solar Measurement
Validate the class of any commercially available contimuous
solar simulator using the SR-500 Spectroradiometer as per IEC60904-9/ASTM E927-05. The graph was generated using theeasy-to-use DARWin SP Data Acquisition and Analysis software
included with each Spectrometer. The green trace shows a radiometric analysis of a solar simulator taken at a customer site.
Built-in software routines automatically provide class status asa function of wavelength and generate a spectral match report.

Rapid one-touch measurements of light emitting diodes canbe obtained using the LF-500 Spectrometer (with optionalcalibration) and the companion DARWin SP Data & Acquisition Module included with each unit. Here, the LF-500 wasused to measure irradiance levels of commercially available
red LEDs (red trace) and yellow LEDs (yellow trace) in two
separate experiments. Easy pull-down menus in the software
allow users to superimpose graphs for convenience.
