CX40M Upright Metallurgical Microscope

Key Benefits

• 100mm working distance provides clearance for probes, tools or sample holders under the objective
• 40X to 400X magnification range covers grain structure, surface defects and micro-hardness testing
• Transmitted light illumination with a 100mm working distance enables inspection of polished metal samples and thin sections
• 10X eyepiece with a 18mm field of view gives a wide view at low magnification
• Fixed 40X and 100X objectives allow quick switching between magnifications without refocusing

Application Scenarios

• Inspecting polished metal samples for grain structure and surface defects in a foundry quality lab
• Checking thin cross-sections of castings or welds under a brightfield illumination system
• Verifying surface finish and microstructure of machined components in a heat-treatment lab
• Performing micro-hardness testing on metal samples with a probe under the optics
• Documenting microstructure features for a quality report using a camera attachment

Who It Is For

• Metallurgy and foundry quality control labs
• Heat-treatment and surface treatment process engineers
• Semiconductor and materials research labs
• Engineering departments inspecting machined or cast components
• Educational labs teaching metallography and materials science

Problems It Solves

• A microscope with no working distance clearance forces the operator to remove the sample to adjust a probe or tool
• Fixed magnification systems require multiple instruments to cover grain structure and fine defect inspection
• Lack of transmitted light illumination makes it impossible to view polished metal samples clearly
• No standard working distance limits the use of probes or tools during inspection
• Separate camera and microscope purchases often fail to match the tube diameter and optical alignment

Technical Features

• Upright design with transmitted light illumination for polished metal and thin section samples
• 100mm working distance under the objective allows room for tools and probes
• Fixed 40X and 100X objectives with a 10X eyepiece provide 400X maximum magnification
• 10X eyepiece with a 18mm field of view for a wide view at low magnification
• Brightfield illumination system with a built-in light source and condenser
• Mechanical stage with 75mm x 50mm travel for moving samples across the field
• Coarse and fine focusing controls for precise depth adjustment
• Standard 10X eyepiece with a 18mm field of view, 10mm focal length

Specifications

Specifications are taken from the AMADA product data for this item. Confirm critical dimensions with us in writing before ordering.

Customization Options

• Monocular or binocular head configuration
• Optional objectives from 20X to 150X to extend the magnification range
• Eyepieces from 15X to 30X to increase total magnification
• Camera upgrade to 1.3MP, 3MP or 5MP USB2.0 CMOS for image capture
• Addition of an Abbe condenser with 1.25NA for higher resolution at high magnification
• Replacement of the standard mechanical stage with a rotating stage for 360° sample viewing

Comparison With Other Options

Use Guide

• Set the working distance to 100mm before placing the sample on the stage to avoid contact with the objective
• Use the coarse focus first, then switch to fine focus for precise depth adjustment
• Ensure the condenser is aligned with the objective for maximum illumination and resolution
• Connect the optional camera to a USB2.0 port; the camera draws power from the same cable
• Use the rotating stage for 360° viewing of a sample without repositioning it manually
