Zeiss presents digital microscope with extended depth of field in real time

Posted on February 18, 2021

With ZEISS Visioner 1, ZEISS is launching an innovative digital microscope that for the first time enables all-in-one focus in real time thanks to its Micro-mirror Array Lens System (MALS). With its extended depth of field, users in their quality control and quality assurance applications in manufacturing can for the first time see the sample completely in focus without having to combine different focal planes from a series of images or post-process them. This not only simplifies the imaging and documentation process, but also allows for faster inspection and therefore higher throughput.

Conventional inspection systems are always challenged by a shallow depth of field, especially at high magnification. This means that only a small area of the sample is in focus, which can lead to features being overlooked and the inspection being incomplete as a result. Extensive refocusing to obtain an extended depth of field, or post-processing, is a solution to this problem, but it is time-consuming and complex. “This is simply a result of the laws of optics,” explains Dr Robert Zarnetta, Head of Industrial Microscopy Solutions at ZEISS in a press release. “Even with the ZEISS Visioner 1, we can’t break this law, of course, but we can bend it in some ways.”
