C5460 Datasheet, PDF (1/4 Pages) Hamamatsu Corporation – APD module

MODULE
APD module
C5460 series
APD module integrated with peripheral circuits
Features
Applications
l Uses high sensitivity APD
l Evaluation of APD
l Two types of APDs with different active areas (φ1.5 mm,
Fluorescence measurement
l ^{φ3.0 mm) are provided.}
l _l On-board high sensitivity circuit optimized for APD evaluation
Bar code readers
Particle counters
l ^{An APD and a low-noise current-to-voltage amplifier circuit}
Film scanners
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^1/2 in the room
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
l Custom models with different dimensions and specifications
are available
