A metallurgical microscope is a specialized type of microscope designed to examine opaque materials, primarily metals and alloys. It uses reflected light to illuminate the sample's surface, unlike biological microscopes that transmit light through the specimen. Here are the key components:

 

Light Source: A powerful light source, often a halogen or LED, is crucial for illuminating the opaque sample.  

Objectives: High-quality objectives with long working distances are essential for focusing on the surface of the sample. These lenses gather light from the sample and magnify the image.  

Illumination System: This includes components like a condenser and filters to control the direction and intensity of light. It ensures proper illumination of the sample for optimal image formation.  

Stage: A sturdy stage is necessary to securely hold the sample in place during examination.  

Eyepieces: Binocular or trinocular eyepieces provide comfortable viewing and can be adjusted for individual eye relief and diopter correction.  

Focusing Mechanisms: Precise coarse and fine focus knobs allow for accurate adjustment of the image.

Frame: A sturdy frame provides support for all the components and ensures stability during operation.
