Do you know what is NETD in a thermal camera?
If you want to know more about netd, follow our website www.ireeda-tech.com.
NETD stands for Noise Equivalent Temperature Difference. It is a parameter that is used to describe the sensitivity of a thermal camera. The NETD value indicates the smallest temperature difference that can be detected by the camera, and it is usually measured in degrees Celsius (or Kelvin). A lower NETD value means that the camera is more sensitive and can detect smaller temperature differences. In general, a good quality thermal camera will have a NETD value of less than 50 mK (milliKelvin), although some high-end cameras can have a NETD value as low as 10 mK.
So, What affects NETD?
NETD is affected by several factors, including the design of the thermal camera and its components. The following are some of the key factors that can affect the NETD value of a thermal camera:
1. Detector size and material: The size and type of detector used in the camera can affect its sensitivity to temperature variations. Larger detectors or those made from more advanced materials like Mercury Cadmium Telluride (MCT) typically offer better performance.
2. Optics: The quality of the lenses used in the camera's optics system can also have an impact on the NETD value. Higher-quality lenses will help to reduce noise and improve the camera's sensitivity.
3. Cooling: Some thermal cameras use cooling systems to keep the detector at a stable temperature, which can help to reduce noise and improve the camera's sensitivity.
4. Electronics: The design and quality of the camera's electronics can also play a role in determining its NETD value. Cameras with better signal processing capabilities will generally be more sensitive, such as Ireeda’s thermal imaging products.
5. Environmental conditions: Environmental factors such as temperature, humidity, and atmospheric conditions can all impact the performance of a thermal camera and affect its NETD value.
In fact, all ireeda thermal imaging products guarantee the optimal value of NETD to ensure the most stable working performance and provide the best price with the least budget.
