Technical Specifications

Experiment Summary

The Kohler illumination experiment helps students understand the optical path design, working principle, and microscopic applications of Kohler illumination by constructing a standardized, uniform, and efficient microscope illumination system.

Experiment Principle

A Kohler illumination module consists of these key components:

Light source: Typically an LED source providing stable, adjustable intensity.
Condenser lens: Collects light from the source and focuses it at the field diaphragm plane.
Field diaphragm: Controls the diameter of the illumination beam projected to the condenser, defines the illuminated area, and eliminates glare.
Condenser and aperture diaphragm: The condenser projects light onto the sample; the aperture diaphragm controls the cone size and shape, affecting brightness and resolution.
Objective lens: Focuses illumination onto the sample and collects reflected/transmitted light to form an image.

Experiment Objectives

Microscope optimization: Master adjustment of the microscope Kohler illumination system and its core role in optimizing imaging.
Separation of illumination and imaging: Understand the principle and benefits of independent control for imaging and illumination optical paths.
Application foundation: Provide theoretical and practical support for microscopic imaging in biology, materials science, and related fields.

Kit List

The Kohler illumination module includes light source components, diaphragm components, lens components, and mechanical components.
