ISO 9022 Standard Part 11 - Testing Microscopes with Severe Conditions

This article describes a test to determine the robustness of Leica microscopes to mold and fungus growth. The test follows the specifications of the ISO 9022 part 11 standard for optical instruments.

Stereo microscopes are often considered the workhorses of laboratories and production sites.

Key Factors to Consider When Selecting a Stereo Microscope

This article explains key factors that help users determine which stereo microscope solution can best meet their needs, depending on the application.

The principle of the FusionOptics technology: Of the two separate beam paths (1), one provides depth of field (2) and the other high resolution (3). In the brain, the two images of the sample are merged into a single, optimal 3D image (4).

What is the FusionOptics Technology?

Leica stereo microscopes with FusionOptics provide optimal 3D perception. The brain merges two images, one with large depth of field and the other with high resolution, into one 3D image.
