Bresser Science MTL 201 Metallurgical Microscope | Lab

Description

Targeting opaque polished alloys and silicon wafer traces, the Bresser Science MTL 201 Metallurgical Microscope | Lab delivers 50x to 800x magnification across an incident light optical train. Widefield 10x eyepieces provide clear framing. The specialized long working distance objectives resolve surface structures, though lack of transmitted illumination prevents inspection of biological thin sections.

An 8.4 kg cast-metal stand houses a quintuple nosepiece with five planachromatic metallurgical objectives (5x, 10x, 20x, 40x, 80x) and a 20W halogen vertical epi-illuminator with field and aperture diaphragms. The solid mechanical stage provides coaxial XY translation for heavy metal samples. Coaxial focus provides fine positioning with an adjustable tension slip, paired with a 30-degree inclined trinocular tube offering 360-degree rotation and an integrated polarizer/analyzer slider set.

Key Features of Bresser Science MTL 201 Metallurgical Microscope | Lab

Metallurgical engineers, foundry quality inspectors, and failure analysis laboratories select this upright microscope to evaluate polished metal grain boundaries and micro-cracks. The dedicated reflected-light illuminator features field and aperture iris diaphragms for Köhler alignment, while long working distance objectives prevent accidental contact with uneven fracture surfaces.

• Vertical 20W halogen epi-illuminator with adjustable field and aperture diaphragms plus color filters
• Solid mechanical stage platform with low-position coaxial XY controls for specimen mapping
• Integrated polarizing filter set with slide-in polarizer and rotatable analyzer blocks

Planachromatic LWD Optics & Epi-Illumination Physics

Long working distance planachromatic objectives eliminate field curvature across polished steel mounts, providing flat edge-to-edge resolution without risk of front lens collisions. The vertical incident 20W halogen illuminator reflects light through an internal half-mirror down the objective axis, while adjustable field and aperture diaphragms eliminate stray glare to highlight alloy phase boundaries, weld porosity, and carbon filaments with high optical contrast.

Stage Mechanics & Polarization Control

The heavy mechanical stage translates large metal parts smoothly across a broad XY coordinate field, supporting dense castings without vertical deflection. Coaxial coarse and fine focus knobs operate with grease-damped precision, while the included polarizer and analyzer sliders cross at 90 degrees to distinguish non-metallic inclusions and anisotropic crystal structures under polarized light.

• Solid stage platform supports heavy metallurgical mounts with smooth, backlash-free XY translation
• Integrated polarizer and analyzer sliders enable instant analysis of birefringent surface films
• Trinocular photo port allows direct attachment of industrial C-mount cameras for digital archival
