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.
