Datasheet C4777-01, C4777 Datasheet (HAMAMATSU)

MODULE

APD module

C4777 series

APD module integrated with peripheral circuits

Features

l

Uses high sensitivity APD
Two types of APDs with different active areas
(φ0.5 mm, φ3.0 mm) are provided.

l

Choice of high sensitivity type and low-light-level detection type
C4777 detects optical signals from 10 kHz to 100 MHz
pulsed light and is suitable for spatial light transmission and
rangefinder applications. C4777-01 provides a high photo­electric sensitivity of 1.25 × 10
making it excellent for fluorescence measurement and NOx
monitors where low-light-level detection is essential.

l

Built-in temperature control circuit
An APD chip, thermoelectric cooler and thermosensor are
sealed in the same package along with the temperature
control circuit, to keep the APD chip temperature constant
and ensure stable measurements.

l

Simple operation
Operates by just connecting to a DC power supply (+5 V, ±15 V).
