Ⅱ The depth of field of an super large depth of field digital microscope is significantly improved compared to a conventional optical microscope, as detailed below:

1. Magnitude of Improvement: The depth of field of a conventional optical microscope is typically between 2-3μm. In contrast, the depth of field of an super-depth-of-field microscope can reach several tens of millimeters. For example, some super-depth-of-field microscopes can achieve a depth of field of 20mm at 500x magnification, which is 40 times greater than the depth of field of a conventional microscope (0.5mm) at the same magnification. Models like the VHX-5000 super-depth-of-field microscope can achieve a maximum depth of field of 34mm, representing an extremely significant improvement.

2. Principle of Improvement: Conventional optical microscopes have a shallow depth of field, only clearly imaging a single focal plane, requiring frequent refocusing for uneven samples. Super-depth-of-field microscopes extend the depth of field through various technologies. In terms of optical design, they use high numerical aperture objectives and aperture diaphragms, adjusting the light source spot size and diaphragm position to vary the focus of light rays at different depths. Simultaneously, combined with software algorithms—such as multi-focal plane image stacking or focus variation methods—images from different focal planes are fused into a fully focused image. Furthermore, through Z-axis scanning, either the stage or the objective is moved to scan the sample layer-by-layer along the Z-axis, acquiring a sequence of 2D images from different focal planes. Subsequent 3D reconstruction then significantly increases the depth range that can be imaged clearly.
