-Typical applications: Diodearray spectrometer for scientific outdoor measurement tasks. Erythema, ICNIRP, solar-cells, etc.
-Calibration: Factory calibrations traceable to PTB calibration standards.
-Typical applications: Lightmeter for spectral Irradiance, Erythema, etc.
-Measured Quantity: Measured Quantity
Spectral irradiance (W/(m² nm)), irradiance (W/m²), peak wavelength, center wavelength, centroid wavelength, Erythema, ICNIRP.
-Input optics: Diffusor, cosine corrected field of view (f2 ≤ 3%)
-Filter wheel: 8 positions (open, closed, optical filters). Use for remote dark current measurement and stray light reduction.
-BiTec: Parallel measurement with diode and array is possible, thereby linearity correction of the array through the diode and online correction of the spectral mismatch of the diode through a*(sz(λ)) respectively F*(sz(λ)).
