8,9,10,11,12,13mm Coaxial LED Ring Light Source for Microscope

Key Benefits

• Coaxial design ensures even illumination directly on the specimen without shadowing
• Adjustable brightness from 0% to 100% allows control over glare and contrast
• Fits 8mm to 13mm diameter microscope tube ends for compatibility with multiple models
• 30000-hour LED life reduces replacement frequency and maintenance
• DC3V output with AC90V-240V input supports global voltage use without a transformer
• 15mm effective light distance and 10mm effective light path ensure focused illumination at the working plane

Application Scenarios

• Inspection of small electronic components under a stereo or biological microscope
• Documenting surface features on metal, plastic or ceramic parts with consistent lighting
• Teaching lab sessions where uniform illumination improves visibility for multiple students
• Quality checks on solder joints, surface finishes or micro-etch patterns
• Use in a variable working distance setup where light must remain centered on the specimen

Who It Is For

• Electronics manufacturers doing PCB, SMD and BGA inspection
• Universities and teaching laboratories using microscopes for practical sessions
• Clinical and research labs requiring consistent illumination for sample observation
• Metallurgy and quality control labs inspecting surface defects and coatings
• Jewellery and watchmaking workshops needing even lighting for fine detail

Problems It Solves

• Uneven lighting from off-axis sources causes shadows and reduces image clarity
• Fixed brightness settings make it hard to adapt to different specimen reflectivity
• Incompatible ring light sizes force users to buy a new light for each microscope model
• Short LED life increases downtime and replacement costs over time
• Lack of coaxial alignment leads to light spill and reduced contrast in high-magnification work

Technical Features

• Coaxial LED ring light with 5W LED for centered illumination
• Adjustable brightness from 0% to 100% via control on the power box
• Effective light distance of 15mm ensures light reaches the working plane
• Effective light path of 10mm maintains focused illumination at the specimen level
• AC90V-240V input with DC3V output supports use in multiple countries
• Aluminum alloy lamp head with split black shell for heat dissipation and durability
• Plastic power box with dimensions 110*60*30mm for compact and stable mounting
• Fits 8mm to 13mm diameter microscope tube ends for broad compatibility
• 30000-hour LED life reduces long-term maintenance needs
