The APD modules are based on low-noise avalanche photodiodes made of InGaAs with a built-in pre-amplifier and high voltage supply.A temperature compensation function allows the APD to be operated at constant gain across a wide operating temperature range.
The APD12703 series photodetector uses a 3mm diameter large target APD photodetector with very high gain and UV enhancement at 355nm, very suitable for fluorescence detection and other scenarios.
APD12702 Series: Temperature compensation, UV-enhanced sensitivity, 3mm photosensitive area. Ideal for low-light signals, fluorescence measurement, and chemical analysis.
