Choice 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.

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 52 g.

Low price

Custom devices available with different dimensions and specifications
