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
