Microscope Lens Technology Technical Guide

This document provides a technical guide on microscope lens technology, focusing on achieving a deep depth-of-field that is 20 times greater than conventional optical microscopes for imaging objects with large surface topography changes. It covers key lens concepts including depth-of-field, numerical aperture, chromatic aberration, working distance, and the structure of zoom lenses, along with techniques to maximize resolution while maintaining a large depth-of-field.
