APD modules
C12702 series
Operates an APD with single 5 V supply
(Standard type, Short-wavelengh type)
Features
Applications
Includes a high-sensitivity APD
Uses a Hamamatsu high-sensitivity Si APD. Four types
are available with different spectral response ranges
and photosensitive areas.
APD evaluation
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 highspeed 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.
Spatial light transmission
Bar code readers
Laser radars
Optical rangefinders
Optical communications
Easy handling
Single 5 V supply operation
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.
Compact and lightweight
The circuit board is no larger than business card size,
and weighs only 37 g.
Low price
Custom designed module available with different dimensions and specifications.
