Extension of the Image Scene Focus Range to a Maximum with EverSharp

The innovative EverSharp function allows all objects in the image scene to be depicted sharply. Users benefit from the function particularly when the depth of field of the lens is rather small and the different measurement objects of the scene are at varying distances from the lens, e.g. when using microscope lenses. Multiple thermal images are created with different focus positions (multifocus images) and combined automatically by means of special algorithms. In the corresponding thermal image, a result consisting of multiple individual acquisitions, all object structures can thus be sharply displayed with the highest possible accuracy. Hence, the entire scene is depicted with greater accuracy and can be measured precisely. This expands the range of applications of the thermographic camera and makes its operation even more convenient. Users recognise each detail of the scene on an entire image. The time-consuming generation of sequential images on which certain details must be subsequently refocused is no longer necessary.
