In using thermal cameras, understanding the limits of measuring distance and contact range is an important step to ensure accurate and reliable temperature measurement results. This EMIN article focuses on important factors such as resolution, instantaneous field of view (IFOV), and spot-size ratio, providing guidance on how to handle situations when measuring objects at different distances each other and provide useful advice to optimize the use of thermal technology. Mastering this information helps users access thermal cameras effectively and reliably, thereby applying it to many different fields with high efficiency.
