-Typical applications: Lightmeter for spectral Irradiance, Erythema, etc.
-Measured Quantity: Spectral irradiance (W/(m² nm)), irradiance (W/m²), peak wavelength, center wavelength, centroid wavelength, Erythema. Option integrating sphere: in addition spectral radiant power (W/nm) and radiant power (W)
-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)).
-Calibration uncertainty:
Spectral irradiance
Spectral irradiance responsivity (200 - 430) nm
-Microprocessor: 32bit for device control,16bit for CCD array control, 8bit for photodiode control
