A Si avalanche photodiode and low noise preamplifier module. A field effect transistor input stage
ensures low HF noise and wide bandwidth. The bias voltage supply has temperature compensation to
maintain the APD. gain constant.
Preferred detector sizes are dia. 0.5 and 2.5 mm. Alternately a
0.5 mm version with lensed cap magnifies the detector (to
~2 mm for beams converging less than 0.1 N.A.). For other
detector diameters — 0.25 to 5 mm in TO52 case, or 0.8 to
2.5 mm in TO5 case, please ask for details.
The amplifier comes with 1.5 metre supply lead and requires ±15V <100mA.
The gain of an APD is temperature sensitive (around –4%/C at gain of 100). A nominal temperature correction
is applied to the bias voltage to reduce this to less than ±1%/C. Improved correction can be done at extra cost,
or the customer can optimize this himself - e.g. if using a different gain. A procedure for setting gain and
temperature correction back to the original values is described in the handbook (all of this assumes a
competent person using anti-static precautions).
Because APDs use high voltages, there may be self heating if >uW intensities are continuously present. The
bias supply is designed to shut down under these conditions.
