UV Radiometer Module / UV Photodiode Evaluation Board

Description

The
evaluation board / radiometer module can be used as an evaluation tool for the performance of the GaN/SiC based UV photodiodes we are able to provide. But with the provided photodiode, it becomes a calibrated tool (ref ELT radiometer) for checking the intensity and dose of your UV light sources using those photodiodes, at a much affordable price. The s
pectral response range is
210-370 nm.
The
evaluation board / radiometer module with one amplifier channel
supports both SMD- and TO-type packaged UV
photodiodes. Users could
select one of the two mounting ports for UV
photodiode evaluation, while both ports should not
be used at the same time.
The evaluation board / radiometer module supports measurement range adjustment function via a dip switch.
Different setting of the dip switch corresponds to different load resistance value, which determines
the amplification magnitude of the signal processing circuit. A temperature sensor on board is used
for embedded temperature compensation.

The UV photodiode evaluation board / radiometer module has both analog and digital output interface. Analog
interface provides voltage signal as a function of UV illumination intensity, while digital interface
provides serial communication to PC with direct digital output. A backside micro-USB port provides
digital interface to PC with USB cable connection. Users could use serial communication host
software in PC to receive direct measurement data from the evaluation board.
