APD module integrated with peripheral circuits

Features

Uses high sensitivity APD

Two types of APDs with different active areas (φ1.5 mm, φ3.0 mm) are provided.

On-board high sensitivity circuit optimized for APD evaluation

An APD and a low-noise current-to-voltage amplifier circuit are mounted on a compact PC board. The current-to-voltage amplifier circuit features a low-noise configuration allowing

low-light-level detection.

Detects optical signals from fixed light (DC light)

C5460 detects optical signals from fixed light (DC light) to 10 MHz pulsed light making it well suited for bar code readers and film scanners. C5460-01 covers a narrower bandwidth from fixed light (DC light) to 100 kHz pulsed light, but provides an excellent NEP of 20 fW/Hz 1/2 in the room temperature, making it suitable for fluorescence measurement and particle counters where low-light-level detection is essential

Built-in temperature-compensated bias power supply

The bias power supply is controlled with a thermosensor to keep the APD gain constant. Gain variations are typically held within ±2.5 at an ambient temperature of 25 ±10 ?C. Ripple noise

usually inherent to high-voltage power supplies is also minimized

Compact and lightweight

The board is no larger than a typical business card.

Low price

Custom models with different dimensions and specifications are available
