HAMAMATSU C5460-01, C5460 Datasheet

MODULE
APD module
C5460 series
APD module integrated with peripheral circuits
Features
l
Uses high sensitivity APD Two types of APDs with different active areas (φ1.5 mm, φ3.0 mm) are provided.
l
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.
l
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 temperature, making it suitable for fluorescence measurement and particle counters where low-light-level detection is essential.
l
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.
l
Compact and lightweight The board is no larger than a typical business card.
l
Low price
