APD module
C10508-01
Variable gain, stable detection even at high gain
The C10508-01 consists of an APD, current-to-voltage converter, high-voltage power supply circuit as well as a microcontroller
for compensating temperature with high stability on the basis of information received from the temperature sensor. The
microcontroller contains coefficients according to the temperature characteristics of the APD. This allows highly stable APD
gain over a wide temperature range even at high gain. The gain can be adjusted using a switch on the circuit board or
commands from a PC.
Features
Gain temperature stability: ±5 % or less
(Gain=250, Ta=0 °C to +40 °C)
Adjustable gain
The gain can be adjusted with a switch or commands
sent from a PC.
Easy handling: Requires only a ±5 V power supply.
Compact and lightweight
Applications
APD evaluation
Optical power meters
Low-light-level detection
