Features |
Applications |
lChoice of high sensitivity APDs
A total of 11 types are available, including 6 types of 800 nm band APDs with active areas from φ0.2 to φ5 mm, 3 types of short-wavelength APDs with active areas from φ1 to φ5 mm, and FC connector types.
lHigh 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.
lEasy handling
Single 5 V supply operation
lBuilt-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.
lCompact and lightweight
The circuit board is no larger than business card size, and weighs only 52 g.
lLow price
lCustom devices available with different dimensions and specifications
