Description
The Spectron Engineering SE590 is a portable battery or A/C operated spectroradiometer consisting of a CE500 data analyzer/logger controller, CE390 spectral detector head and an external battery charger/power supply. The CE500 is a self contained microprocessor based controller which processes the signal from the detector head, amplifying and digitizing it with 12 bit resolution. For each spectral scan, the controller actuates the CE390 shutter, measures and stores the dark current, calculates optimum integration time, acquires the spectrum and automatically subtracts the noise for all 256 spectral elements. A series of scans can be taken and automatically averaged. The spectrum is stored in a double precision register which saves the entire 12-bit binary spectra until it is transmitted through the RS-232C port. The spectral detector head uses a diffraction grating as the dispersing element; the spectrum is imaged onto a 256 element photo diode array. Each element integrates simultaneously acquiring the spectrum in a fraction of a second. The interconnect cable from the spectral head to the controller couples the spectral signals to the controller, and the timing and control signals to the detector head. A shutter in the detector head, operated by the controller, closes the light path for dark current measurements. For further information consult the SE590 operating manual.
Field of View (FOV)
The SE590 camera head has interchangeable lens that can use a 1o and 15o FOV. If no lens is used the FOV is 6o. A straight-through lens can be used as an adapter to attach the spectroradiometer to an integrating sphere. A fiber optic cable can be attached to the camera head. A hemispherical view adapter can be attached to the camera head.
