APD module
C5331 series
Operates an APD with single 5 V supply
l
Choice of high sensitivity APDs
A total of 11 types are available, including 6 types of 800 nm band APDs with
active areas from
φ
0.2 to
φ
5 mm, 3 types of short-wavelength APDs with active
areas from
φ
1 to
φ
5 mm, and FC connector types.
l
High sensitivity detection board optimized for APD evaluation
An APD and high-speed current-to-voltage amplifier circuit are mounted on a
compact board. The high-speed current-to-voltage amplifier circuit features a
low-noise configuration ideal for the APD signal readout and operates at high
speeds yet with high sensitivity.
l
Easy handling
Single 5 V supply operation
l
Built-in temperature-compensated bias voltage circuit
Controls the bias voltage with a thermosensor to keep the APD gain constant.
Gain is stabilized to as low as ±2.5 % Typ. at ambient temperatures of 25 ±10 C.
Ripple noise usually inherent to high voltage power supplies is also minimized.
l
Compact and lightweight
The circuit board is no larger than business card size, and weighs only 52 g.
l
Low price
l
Custom devices available with different dimensions and specifications
