With the Zeiss Visioner 1, Zeiss launched in the first quarter of 2021 an innovative digital microscope that, for the first time, allows, in real time, automated focus over the entire depth of field, thanks to its system of micro-mirror lenses (Mals).
Its extended depth of field (EDoF) will satisfy users who will be able to observe the samples to be controlled without having to combine and post-process different focal planes from a series of images. This not only simplifies the imaging and documentation processes, but also allows for faster inspection and therefore higher productivity.
Extended depth of field in real time
Conventional inspection systems always face a shallow depth of field, especially at high magnification. This means that only a small area of the sample is developed, which can lead to neglect of features and, as a result, make the inspection incomplete. To obtain a greater depth of field, redoing the focus and then performing a post-processing is a solution to this problem; but it is long and complex.
Mals technology
The alternative is the use of Mals technology. It is a micro-electromechanical system (Mems) consisting of a matrix of small mirrors measuring 100 x 100 μm. These can be adjusted individually to generate "virtual" lenses with different curvatures and therefore different focus planes. This allows the digital microscope to accurately image any point in the sample. The result is an extended depth of field 100 times greater than that of conventional digital microscopes. It also offers the possibility to optically inspect height differences up to 69 mm without having to move the optical system or redo the focus. The 3D information of the sample is visible at a glance, allowing for faster and more reliable inspection.
Ergonomic operation, rapid visualization and documentation of samples
The Zeiss Visioner 1 accelerates visual control processes, making it possible to inspect more components in less time, with improved comfort of use. Zeiss Zen imaging software, intuitive and workflow-oriented, greatly simplifies visual inspection and sample documentation and offers a particularly relevant complement for highly regulated industries, such as automotive, aerospace or medical, with important verification requirements that rely on compliance with GxP guidelines.
