Gigahertz-Optik BTS2048-UV-S High-quality compact spectroradiometer (190 - 430 nm)

-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

-Interface: USB V2.0, Ethernet (LAN UDP protocol), RS232, RS485

-Data transfer: Standard for 2048 float array values via ethernet 7ms, via USB 2.0 140 ms

-Input Interfaces: 2x (0 - 25) VDC, 1x optocoupler isolated 5 V / 5 mA

-Output Interfaces: 2x open collector, max. 25 V, max. 500 mA

-Trigger: Trigger input incorporated (different options, rising/falling edge, delayed, etc.)
