Reliable NIR Performance
The standard InGaAs photodiodes provide reliable, low-noise detection across the near-infrared spectrum. Designed for precision measurement, they convert NIR light into stable electrical signals with high sensitivity, supporting wavelengths from approximately 850 nm to 1700 nm, with extended options available for longer ranges.
The product family includes both small- and large-area photodiodes to address different performance requirements.
Small- and Large-Area Standard InGaAs Photodiodes
- Small-area InGaAs Photodiodes offer fast response and low capacitance, making them well-suited for high-speed measurements.
- Large-area InGaAs Photodiodes capture more light, enabling higher sensitivity and better performance with larger beam sizes.
A variety of package styles, window options, and cooling configurations allow each device to be tailored to specific applications. These photodiodes are commonly used in NIR sensing, spectroscopy, laser and LED characterization, medical instrumentation, and telecom and datacom monitoring. Clear performance specifications enable engineers to easily compare models and select the optimal balance of speed, sensitivity, and active area for their systems.
