Operates an APD with single 5 V supply (Standard type, Short-wavelengh type)
FEATUREs
◾ Includes a high-sensitivity APD
Uses a Hamamatsu high-sensitivity Si APD. Four types
are available with different spectral response ranges
and photosensitive areas.
◾ 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.
◾ 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.
APPLICATIONs
◾ APD evaluation
