LAWRENCE, Mass., Aug. 20, 2013 — Spectral Evolution’s SR-1100-TE spectroradiometer has a 320- to 1100-nm spectral range designed for radiometric calibration transfer involving satellite sensors and integrated spheres. The device features a 512-element TE-cooled silicon photodiode array with temperature control across a wide range of environments, as well as auto-temperature control at ambient temperatures of 15 to 40 °C. It also offers a minimum scan speed of 100 ms, a spectral resolution of <3.2 nm and a sampling bandwidth of 1.5 nm. The spectroradiometer features diffraction-based optics, auto dark current shutter and auto exposure for one-touch operation, as well as a fixed metal-clad fiber optic cable with SMA-905 input and removable fiber. Equipped with DARWin SP data acquisition software, the device can store data as ASCII files to be used with third party analysis software as well as calculate integrated radiance and irradiance for an active spectrum over a user-adjustable wavelength band.
