Upright Metallurgical Microscope | Reflected Brightfield | Plan Epi

A metallurgical microscope is a high-power optical instrument used to view opaque specimens like metals, ceramics, plastics, and semiconductor wafers. It is critical for industrial quality control, failure analysis, coating thickness measurement, and analyzing grain boundaries.

Also known as incident illumination, this system shines light down *through* the objective lens onto the solid specimen. The light then reflects off the surface of the metal and travels back up through the same lens to your eyes.

In Brightfield (BF) metallurgical microscopy, the light hits the specimen perpendicular to its surface. Flat areas reflect light directly back (appearing bright), while angled areas, scratches, or grain boundaries scatter light (appearing dark). This creates a high-contrast image of surface structures.

Brightfield (BF) shows flat surfaces as bright and anomalies as dark. Darkfield (DF) uses oblique lighting so flat surfaces appear black, and only the light scattered by scratches, cracks, or edges enters the lens, making anomalies glow brightly against a dark background.

Epi-illumination is simply the technical term for "reflected light" illumination, where the light source is above the specimen and passes down through the objective lens.

Plan Epi objectives are specialized lenses designed specifically for viewing opaque materials under reflected light without cover slips. The 'Plan' designation means they provide a completely flat, distortion-free field of view from edge to edge.

The GBS.13.2604-A offers 50x to 500x magnification utilizing the standard WF10x/22mm eyepieces and the high-resolution Plan Epi 5x, 10x, 20x, and 50x objectives.

Kohler illumination is a precise alignment of lenses and irises in the lighting path that ensures perfectly even, bright illumination across the entire field of view, minimizing glare and maximizing specimen contrast.

Any opaque material can be examined, including steel, aluminum, cast iron, copper, ceramics, semiconductor wafers, printed circuit boards (PCBs), plastics, and painted/coated surfaces.

Biological microscopes use transmitted light passing *through* thin, transparent samples on glass slides. Metallurgical microscopes use reflected light bouncing *off* solid, opaque samples that light cannot pass through.

These are standard in automotive foundries, aerospace manufacturing, semiconductor fabs, material science university departments, and forensic failure analysis laboratories.

The brightfield metallurgical microscope price varies based on optics (Plan vs Achromatic) and illumination type. Please request a quote for the most accurate industrial pricing from GBS Microscopes.

It is the process of examining the crystalline structure of metals. After a metal sample is polished and chemically etched, the metallurgical microscope reveals the boundaries between different crystal "grains", which dictates the metal's strength and properties.

An upright microscope looks down onto the top of a specimen, restricting the height of the sample you can view. An inverted microscope looks up from underneath the specimen, allowing you to place massive, heavy metal parts on the stage without height restrictions.

Yes, the trinocular head allows you to easily connect standard digital microscope cameras via a C-mount adapter for capturing high-resolution images of grain structures and defects.

Industries include steel manufacturing, automotive parts casting, aerospace engineering, electronics (PCB inspection), and any field requiring strict verification of metal heat treatments and weld seams.
