XUM800 Upright Metallurgical Microscope
The XUM800 is an upright metallurgical microscope with a binocular or trinocular head, infinity plan achromatic objectives, and Kohler illumination.

Product Overview
The XUM800 is an upright metallurgical microscope with a binocular or trinocular head, infinity plan achromatic objectives, and Kohler illumination. It supports 4X to 100X magnification with a working distance from 17.3mm down to 0.32mm. The system is designed for metallographic inspection, including grain structure, surface defects and microhardness testing, with a double-layer mechanical stage and coaxial coarse and fine focusing for stable operation.

Key Benefits
- Infinity optical system with plan achromatic objectives ensures flat, distortion-free images across the field
- Kohler illumination with adjustable iris aperture and field diaphragm provides even, glare-free lighting for surface detail
- Double-layer mechanical stage (150x140mm / 75x50mm) allows large specimens and precise positioning
- Coaxial coarse and fine focusing enables smooth, stable focus adjustment without shifting the specimen
- Binocular or trinocular head configuration allows simultaneous observation and digital imaging
- Working distance ranges from 17.3mm (4X) to 0.32mm (50X), suitable for both large samples and high-magnification surface analysis
Application Scenarios
- Metallographic inspection of castings, welds and heat-treated steel samples in a quality lab
- Surface defect analysis on machined or polished metal parts for failure root cause investigation
- Microhardness testing preparation with a specimen presser for consistent sample mounting
- Educational demonstration of grain structure and phase boundaries in metallurgy teaching labs
- Documentation of microstructure images with a camera attached to the trinocular port
Who It Is For
- Metallurgy, foundry and heat-treatment quality control labs
- Materials science and engineering departments in universities
- Research labs conducting microstructure analysis of metals and alloys
- Manufacturing quality teams inspecting tool steels, cast iron, aluminum and titanium components
- Training centers teaching metallography and microstructural evaluation
Problems It Solves
- Fixed focus or non-coaxial focusing systems make it difficult to maintain specimen position during high-magnification inspection
- Poor illumination causes glare and shadowing on polished metal surfaces, hiding surface features
- Lack of a mechanical stage forces manual handling of samples, increasing risk of damage and misalignment
- No option for digital capture means inspection results must be described or hand-drawn
- Short working distance at high magnification prevents use of standard tools or probes near the specimen
Technical Features
- Infinity optical system with plan achromatic objectives for flat, high-contrast images
- Kohler illumination with iris aperture and field diaphragm for uniform, adjustable lighting
- Double-layer mechanical stage with 150x140mm and 75x50mm travel ranges for large and small specimens
- Coaxial coarse and fine focusing with a 20mm travel range for stable, repeatable focus
- 6V/20W halogen lamp with brightness adjustment for consistent illumination intensity
- Binocular or trinocular head with optional 0.1mm micrometer and crosshair eyepiece for precise measurement
- Specimen presser included for secure mounting of polished metal samples
- Interchangeable objectives from 4X to 100X with working distances from 17.3mm to 0.32mm

Comparison With Other Options
| XUM801 Upright Metallurgical Microscope | The XUM800 includes a trinocular head as standard; the XUM801 offers it only as optional. |
|---|---|
| XUM802 Upright Metallurgical Microscope | The XUM802 has a trinocular head and a different set of objectives; the XUM800 offers more objective options including 50X and 100X with specified working distances. |
| Traditional metallurgical microscope with simple illumination | The XUM800 uses Kohler illumination with adjustable diaphragms, reducing glare and improving contrast compared to basic epi-illumination systems. |
Use Guide
- Adjust the interpupillary distance to match your eye spacing before focusing to avoid eye strain
- Use the coarse focus first at low magnification, then switch to fine focus for precise adjustment
- Align the Kohler illumination by adjusting the condenser and diaphragms for even lighting across the field
- Mount the specimen securely using the specimen presser to prevent movement during high-magnification inspection
- Select the appropriate objective based on required magnification and working distance for the sample
