UV-3726 Irradiance Detector for UV-C LEDs and low-pressure Hg lamps

The UV-3726 model offers all the properties and features of the UV-37
series detectors. They are specially designed for radiometric measurementtasks in the UV spectral region and have been proven in industrial andscientific use over many years.
The UV-3726 detector incorporates a photodiode that is only sensitive inthe short-wave spectral range. In conjunction with additional opticalfiltering, only radiation in the specified spectral sensitivity range ismeasured. This combination enables the radiometric measurement of UV-Typical spectral sensitivity of theUV-3726 detector shown together

C LEDs and low-pressure mercury lamps. Selectable calibration factors forcommon UV LED wavelengths and low-pressure Hg lamps increase themeasuring accuracy.
To measure the irradiance, the detector’s entrance optic is a diffuser with acosine field of view, which must be positioned in the desired plane ofmeasurement. The diffuser, optical correction filter and photodiode are
pre-aged with UV radiation to significantly reduce the inevitable aging
process that results from exposure to UV radiation. The UV-3726 detector
shows very little aging effects even in intensive use. Any changes arerecorded and corrected as part of the recommended annual recalibration.
The photodiode of the UV-3726 detector offers a strictly linear relationshipbetween the measurement signal and the irradiance in the range from a

few pico amps (10-12 A) to several micro amps (10-6 A). When connected tothe Gigahertz-Optik X1-1-V02 meter it provides a linear measurement
range up to at least 1000 mW / cm² with a resolution of 0.002 µW / cm².
Calibration

Reliable measurements in absolute units require the calibration of themeasuring device with traceability to national metrological institute (NMI)
standards. Since 1993, the Gigahertz-Optik measuring laboratory has been
accredited as a calibration laboratory by the PTB (Physikalisch-TechnischeBundesanstalt) and the DAkkS (German Accreditation Body) for themeasurement of spectral responsivity and spectral irradiance. Since then,
all factory calibrations have been closely based on the calibration

standards and quality management of the accredited calibrationlaboratory. Therefore, the factory calibrations of Gigahertz-Optik offer thehighest possible level of traceability and have been accepted worldwide formany years.
In accordance with the requirements of individual industrial sectors, partof the measuring laboratory is accredited by the DAkkS as a DIN EN ISO /IEC 17025 test laboratory.

The UV-3726 detector is calibrated for its spectral responsivity. Whenperforming a measurement, the nominal wavelength of the UV-LED or Hg
lamp can be selected on the X1-1-V02 meter for highest precision. The
meter offers several calibration options:An average calibration factor for measuring any UV LEDs in the spectral range
from 260 nm to 290 nm.
A specific calibration factor for measuring low-pressure Hg lamps (at 254nm).
Eleven, wavelength dependent, calibration factors given in 5 nm increments from 250
to 300 nm for measuring UV LEDs with known nominal wavelength.
