QP-PR-1G 2um analog light detection module integrates high-speed enhanced InGaAs detector and low noise amplifier, single-mode fiber or free space coupling, SMA connector output, having high gain. High sensitivity, gain flat and other characteristics are mainly used in infrared doped Tm, Ho fiber laser testing, gas and water molecules detection, and other fields.
Features:
- Spectral range：900-2300nm
- Low noise
- High gain
- Single -mode fiber or free space coupling optional
- Compact structure,Anti - electromagnetic interference
- Can be customized according to customer requirements (built-in PIN tube photosensitive surface optional)
Applications:
- Weak signal detection
- Analog signal detection
- Water molecule detection
- Doped Tm, Ho fiber laser test
- Picosecond mid - infrared laser pulse detection
