Trinocular Metallurgical Microscope | Transmitted Reflected Light BF DF

This dual-illumination system allows the microscope to analyze both opaque materials (like metals and semiconductors) using reflected light from above, and transparent materials (like thin films, crystals, and plastics) using transmitted light from below, making it incredibly versatile for material analysis.

Reflected (Episcopic) light bounces off the surface of solid, opaque objects to reveal surface details like grain boundaries or corrosion. Transmitted (Diascopic) light passes *through* transparent or translucent samples to reveal internal structures, much like a standard biological microscope.

Having dual illumination means one single microscope can inspect virtually any material type. You can examine solid PCBs, wafers, and steel using reflected epi-illumination, and then switch to transmitted light to observe translucent polymers, LCD panels, and optical fibers.

It is perfectly suited for a massive range of materials including metal alloys, steel grains, ceramics, dense polymers, semiconductors, PCBs, integrated circuits, glass, transparent plastics, and thin films.

In Brightfield (BF), direct light reflects off the specimen into the objective, creating a bright background where flat surfaces appear bright and crevices appear dark. In Darkfield (DF), direct light is blocked, and only light scattered by surface imperfections (like scratches, edges, or structural boundaries) enters the objective, making those specific features glow brightly against a pure black background.

Infinity Plan objectives are specialized optical lenses that correct for chromatic aberration and field curvature. They produce a perfectly flat field of view (edge-to-edge sharpness) without distortion, and the parallel light path allows advanced components like polarizers to be inserted without degrading image quality.

It consists of a polarizer and an analyzer. This attachment is used to observe materials that have crystalline or birefringent properties under polarized light, greatly enhancing contrast for specific minerals and metal alloys.

Long Working Distance (LWD) objectives provide greater physical space between the tip of the lens and the specimen. This allows you to safely inspect thicker, uneven, or awkwardly shaped industrial materials without the lens crashing into the sample.

The field diaphragm controls the diameter of the light beam, reducing peripheral glare to improve image contrast. The aperture diaphragm adjusts the cone angle of the light, allowing the user to balance resolution and contrast perfectly depending on how reflective the metallic surface is.

Kohler illumination is a specialized optical alignment that provides incredibly even, bright, and perfectly focused light across the entire specimen field. It provides crisp, heat-free imaging for high-magnification digital photography.

The 175x145mm dimension refers to the large double-layer mechanical stage. This oversized platform provides maximum stability for heavy industrial samples, allowing for a smooth 76x42mm X-Y travel range without sample vibration. The TR model includes a glass plate for the transmitted light to pass through.

These highly versatile microscopes are standard in university materials science departments, semiconductor manufacturing plants, automotive metallurgy labs, aerospace quality control centers, and forensics laboratories across India.

An upright microscope (like this model) has the objectives above the stage looking down, which is great for standard-sized samples and dual-light operation. An inverted microscope has the objectives below the stage looking up, which is useful for observing extremely large or heavy metallic chunks.

Yes, because of the infinity-corrected optical path, this microscope easily accepts polarizing attachments. It acts as an excellent base if you need to upgrade for advanced research techniques.
