Laser Pulse Parameter Measurement——Photoelectric Detector |
|
|
|
CNI
presents bias photodetectors and amplified photodetectors,
supporting two measurement modes: free-space and fiber-optic
interface. Widely adopted in industrial production and
scientific research, these devices convert optical signals into
electrical signals, allowing oscilloscopes to read relevant
parameters such as waveform, pulse width, frequency and period.

Testing Instrument:
Photoelectric Detector |
|
The D-series
photodetectors are bias photodetectors,
well-suited for monitoring fast pulsed lasers
and measuring parameters such as pulse width,
rise time, repetition rate, and period. Each
detector is equipped with an attenuator, which
can be installed or removed freely according to
the incident optical power. In addition, a 50 Ω
load resistor is recommended for high-speed
signal detection. |

The DA-series
photodetectors are
silicon-based amplified
photodetectors featuring
a fixed maximum
bandwidth and total
transimpedance gain.
Each detector is
equipped with an
attenuator, which can be
installed or removed
flexibly according to
the incident optical
power. In addition, each
amplified photodetector
requires a ±12 V linear
power supply. Our
company can supply
self-developed linear
power supplies. |
