APD module integrated with peripheral circuits

Features

● Uses high sensitivity APD

Two types of APDs with different active areas

(φ0.5 mm, φ3.0 mm) are provided.

● 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 × 109 V/W and low NEP of 2 fW/Hz1/2,

making it excellent for fluorescence measurement and NOx

monitors where low-light-level detection is essential.

● 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.

● Simple operation

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