Upright Metallurgical Microscope | Reflected & Transmitted | Plan Epi

This dual-illumination microscope is incredibly versatile. It uses reflected light to inspect solid, opaque metals and ceramics, while the transmitted light allows you to observe transparent or semi-transparent materials, thin films, plastics, and resins.

Reflected illumination shines light down onto the surface of an opaque sample from above the objective lens. Transmitted illumination shines light up through a transparent or translucent sample from beneath the stage.

Brightfield illuminates the sample directly. For reflected light, flat surfaces appear bright while scratches and grain boundaries appear dark. For transmitted light, the background is bright, and the specimen absorbs or blocks light to create contrast.

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.

You can observe virtually anything: solid steel blocks, forged aluminum, cast iron, semiconductor wafers, printed circuit boards (PCBs), as well as transparent plastics, glass, crystal sections, and coated films.

Plan Epi objectives are specialized lenses designed specifically for viewing opaque materials 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-B offers 50x to 500x magnification utilizing the standard WF10x/22mm eyepieces and the high-resolution Plan Epi 5x, 10x, 20x, and 50x objectives.

Dual Kohler illumination means that both the top (reflected) and bottom (transmitted) light sources are optically aligned to provide perfectly even, glare-free, high-contrast light, essential for high-magnification research.

It is perfect for mixed-media applications: opaque materials like copper, brass, alloys, and ceramics, alongside transparent materials like polymers, resin mounts, thin films, and liquid crystal displays.

A reflected-only microscope can only view solid, opaque objects. A reflected-transmitted (dual illumination) microscope adds a light source under the stage, allowing you to also view transparent and translucent specimens.

These are standard in advanced material science university departments, semiconductor fabs, aerospace engineering labs, and industrial quality control centers that handle both metal parts and plastic/resin components.

It is the process of examining the crystalline structure of metals. After a metal sample is polished and chemically etched, the reflected light 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 transparent sections simultaneously.

Industries include semiconductor manufacturing, electronics (PCB inspection), aerospace engineering, polymer processing, and any field requiring strict verification of both metal heat treatments and transparent protective coatings.
