Deep Understanding of CQDs CMOS SWIR Cameras
CQDs CMOS image sensors are a new type of short-wave infrared (SWIR) imaging technology that uses Colloidal Quantum Dots as photosensitive materials and deeply integrates with standard CMOS processes. Compared to traditional InGaAs solutions, CQDs CMOS sensors offer advantages such as high cost-effectiveness, high resolution, compact size, suitability for large-scale mass production, and environmental friendliness, promoting SWIR imaging from high-end scientific research to broader industrial, agricultural, and consumer-level applications.
The absorption peak of CQDs materials can be flexibly customized by adjusting quantum dot particle sizes, enabling a single chip to cover a broad wavelength band from approximately 300–1700 nm or even extended to 2500 nm. Their quantum efficiency, dynamic range, and signal-to-noise ratio continue to improve, with some models capable of room temperature low-noise imaging and optional TEC cooling for high-requirement scenarios.
CQDs CMOS SWIR cameras feature standard optical interfaces and compact module designs for easy system integration and large-scale applications, making them ideal solutions for industrial inspection, material analysis, semiconductors, agricultural sorting, machine vision, food and pharmaceutical testing, and other fields.
