If you want to know the product details and prices, or If the parameters are not suitable, you can contact me for customization.
Overview
The balanced photodetector module contains two photodiodes and a low-noise transimpedance amplifier，Two of the photodiodes are matched to achieve an excellent common-mode rejection ratio，The detector differentiates the two detection signals to eliminate common-mode noise, which can obtain small changes in the effective signal from the interference noise。
Features
- Two wavelength ranges are available
- All-metal shell with excellent shielding performance
- Excellent common-mode rejection ratio
Application
- DVS/DAS
- Fiber optic sensing
- Coherent detection
- Wind radar
- OCT
