Introduction to the product and its size chart：

This product is an avalanche photodiode (APD) made of indium gallium arsenide material. It enhances the photoelectric conversion gain through the avalanche effect, resulting in higher sensitivity, making it suitable for weak light signal detection. Its photosensitive range covers 900nm to 1700nm, and it is commonly used in near-infrared light measurement. As an amplifying detector, it has a fixed gain, enabling quantitative photoelectric conversion. Moreover, it is seamlessly compatible with the same type of products from THORLABS, featuring excellent performance and high cost-effectiveness. It also provides comprehensive technical support and non-standard customization services.
