G12180-003A Infrared Photoelectric Sensor (InGaAs PIN photodiode) For Laser Monitoring Systems
1. Application Areas:
Laser Monitoring Systems: Enables real-time detection and monitoring of laser output intensity in industrial laser processing, medical laser equipment, and research-grade laser setups, ensuring stable laser performance.
Optical Power Meters: Serves as a core sensing component in optical power measurement devices, accurately capturing near-infrared (NIR) optical power signals for applications like fiber optic testing and laboratory photometry.
Laser Diode Life-Cycle Testing: Withstands long-term operation and maintains consistent responsiveness, making it suitable for evaluating the durability and performance degradation of laser diodes over their service life.
Near-Infrared (NIR) Photometry: Facilitates precise measurement of NIR light absorption, transmission, or reflection in fields such as biochemical analysis, material science, and environmental monitoring.
Optical Communication Systems: Detects high-speed NIR optical signals (e.g., in 1.3 μm or 1.55 μm wavelength bands) for use in fiber optic communication transceivers, ensuring reliable data transmission in telecom networks.
2. Key Features:
Broad NIR Spectral Response: Operates across a wavelength range of 0.9–1.7 μm, covering critical bands for optical communications, laser applications, and NIR photometry.
High Sensitivity: Delivers a typical photosensitivity of 1.1 A/W (at peak wavelength ~1.55 μm), enabling accurate detection of low-intensity NIR optical signals.
Low Dark Current: Features a maximum dark current of 0.5 nA (under reverse voltage VR = 5V), minimizing background noise and improving signal-to-noise ratio (SNR) for precise measurements.
High-Speed Performance: Boasts a typical cut-off frequency of 600 MHz, supporting high-speed signal detection for applications like fast optical communication or laser pulse monitoring.
Compact & Robust Package: Housed in a TO-18 package (a standard, compact metal package), ensuring mechanical stability, easy integration into circuit designs, and compatibility with standard optical mounting setups.
Wide Operating Temperature Range: Functions reliably in temperatures from -40°C to 100°C, making it suitable for harsh industrial environments or outdoor applications.
Low Junction Capacitance: Has a typical junction capacitance of 5 pF (VR = 5V), reducing signal distortion and enhancing high-frequency performance.
