Inverted Metallurgical Microscope | Reflected Light | Infinity Plan

An inverted metallurgical microscope is used for observing the microstructure, grain boundaries, and defects of opaque materials like metals, alloys, ceramics, and semiconductors, especially when the samples are too large, heavy, or irregularly shaped for a standard upright microscope.

An upright microscope looks down onto the top of a specimen, severely 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.

Reflected light brightfield illumination shoots light up through the objective lens, bounces it off the flat, polished surface of the opaque specimen, and reflects it back into the lens. Flat surfaces appear bright, while cracks or grain boundaries scatter the light and appear dark.

Because the objectives are underneath the stage pointing upward, there is physically no structure above the stage to block the sample. You can literally place an entire engine block or large steel pipe directly onto the stage for analysis.

Aside from handling oversized samples, the major advantage is sample preparation. With an inverted microscope, only the single side facing downward needs to be perfectly flat and polished. The rest of the sample shape does not matter.

Infinity Plan objectives are specialized lenses optimized for viewing solid, opaque specimens without the need for a glass coverslip. The 'Plan' designation ensures the entire field of view is completely flat and perfectly in focus from edge to edge.

The GBS.13.2606 offers 50x to 500x magnification utilizing the standard WF10x/22mm eyepieces and the high-resolution Infinity Plan 5x, 10x, 20x, and 50x objectives.

Kohler epi-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 large steel slabs, aluminum castings, cast iron, copper alloys, ceramics, semiconductor wafers, plastics, and thick painted or coated surfaces.

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.

These are the workhorses of automotive foundries, aerospace manufacturing, heavy metallurgy material science university departments, and industrial failure analysis laboratories.

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

Yes, the inverted reflected light metallurgical microscope with camera port for digital image documentation allows you to easily connect standard digital microscope cameras via a C-mount adapter for capturing high-resolution images of grain structures.

Industries include heavy steel manufacturing, automotive engine block casting, aerospace engineering, piping, and any field requiring strict verification of metal heat treatments and weld seams on oversized components.

The massive 3-layer stage provides extreme durability and smoothness. It allows technicians to mount incredibly heavy metal samples and still use the X/Y coaxial knobs to glide the specimen around flawlessly for analysis without dragging or stuttering.
