Quantum dots are semiconductor nanocrystals with distinct optoelectronic properties. Typically only a few nanometers in size (10^-9 meters), they confine electrons to a very small space, resulting in what is known as the quantum confinement effect. A defining characteristic of quantum dots is that their light absorption and emission wavelengths vary based on their size. Smaller quantum dots emit shorter wavelengths (blue or ultraviolet), while larger ones emit longer wavelengths (red). Due to these unique properties, quantum dots are widely used in displays, bioimaging, image sensors, and more.
Thanks to their quantum mechanical features, quantum dot cameras deliver high sensitivity even in low-light conditions, enabling them to capture high-resolution images in dim environments. This makes them ideal for use in military facilities, semiconductor and IT manufacturing sites, as well as in agriculture.
The SDT quantum dot SWIR camera harnesses the unique properties of quantum dots to effectively penetrate smoke, fog, and dust, ensuring clear target identification. Unlike InGaAs cameras, which require rare materials and specialized equipment for production, quantum dot sensors can utilize existing semiconductor manufacturing infrastructure. This allows for mass production at a much lower cost compared to other technologies, making it a more accessible and cost-effective solution for a variety of applications.
