Detector_QuantumCTek– Quantum Secures Every Bit

: InGaAs Avalanche Photo Detector

<p>This product is a compact near-infrared avalanche photodetector with a core circuit made of domestically produced lnGaAs/lnP APd with independent intellectual property rights. It has characteristics such as high gain, high sensitivity, and low noise. It can provide a cost-effective solution for near-infrared weak light detection and measurement of short pulse signals, and is widely used in fields such as laser communication and LiDAR. <p>

<p>This product operates in linear mode and integrates a low-noise broadband transimpedance amplifier, achieving a maximum conversion gain of 5.2✖106V/W and supporting gain adjustment; Using temperature compensation circuit to achieve temperature stability control of signal amplification factor. The diameter of the photosensitive surface reaches 200 µm. At a working bandwidth of 10MHz, the noise equivalent power is as low as 0.35nW; Support free space coupling and fiber optic coupling; Meanwhile, the internally integrated strong light injection protection function enables the product to have higher environmental adaptability. <p>
