APD1050H Avalanche Detector
This APD avalanche-photodetector series operates essentially like Thorlabs/Newport detectors and uses identical power connectors. It is stated to directly replace equal-bandwidth models when a Monitor output, present on some Thorlabs/Newport products, is unnecessary, with comparable or better performance. 广州瑞东's APD detectors are fully domestically produced. Proprietary temperature compensation gives high sensitivity, stability/gain and low noise across -40°C to 80°C. Standard models and customization of supply voltage, gain, bandwidth and other specifications are available. Uses include lidar, free-space optical communications, fiber sensing and optical inspection.
