AJ-A HandHeld Portable Metallurgical Microscope with Polarizer

Key Benefits

• Handheld design allows inspection in tight spaces, on-site, or at the production line
• Polarizer enables detection of stress, strain, and crystal structure in metals and alloys
• Adjustable LED illumination (3.6V) provides consistent light without heat buildup
• 0.5mm to 7.3mm working distance suits thin, polished, or fragile metal samples
• 100X to 400X magnification range covers grain structure, surface defects, and micro-hardness testing

Application Scenarios

• On-site inspection of metal parts in a foundry or heat-treatment facility
• Checking grain structure and surface defects in a metal sample after polishing
• Detecting internal stress or crystal orientation in a machined component using polarized light
• Field testing of metal fatigue or wear patterns on a production floor
• Quality control of thin metal foils, coatings, or plated layers in a manufacturing line

Who It Is For

• Metallurgy and materials testing labs in manufacturing plants
• Foundry and heat-treatment quality control technicians
• Field engineers inspecting metal components at the job site
• Research labs studying microstructure of metals and alloys
• Maintenance teams diagnosing wear or failure in metal parts

Problems It Solves

• A fixed-position microscope cannot be used in confined or mobile inspection environments
• Lack of polarizer prevents detection of internal stress or crystal anisotropy in metals
• Fixed illumination sources may cause glare or shadowing on polished metal surfaces
• Short working distance instruments risk damaging the sample or objective during focus
• No portable solution forces the operator to transport samples to a lab for inspection

Technical Features

• Monocular head with 23.2mm mounting size for eyepiece compatibility
• Polarizer integrated into the optical path for stress and crystal analysis
• Adjustable LED illumination (3.6V) with no thermal load on the sample
• 160mm tube length ensures consistent optical alignment across magnifications
• 36mm focusing range allows for variation in sample thickness and surface height

Specifications

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

Customization Options

• Option to replace the standard 10X eyepiece with other magnifications if available
• Use of auxiliary objectives or adapters to extend magnification or working distance
• Integration of external polarizing filters or analyzer components if required
• Mounting on a tripod or stand for hands-free operation if needed

Comparison With Other Options

Use Guide

• Set the LED illumination to the lowest intensity first, then increase to avoid overexposure on polished metal surfaces
• Use the polarizer by rotating the filter to observe changes in contrast and birefringence
• Start with the lowest objective (4X) to locate the area of interest, then switch to higher magnifications
• Keep the working distance between 0.5mm and 7.3mm to avoid contact between the objective and the sample
• Ensure the sample surface is clean and polished for clear imaging of microstructure
