16pcs Polarized LED Ring Lights for Microscope AM-16-Polarized

Key Benefits

• 16 individual polarized LEDs provide even, glare-free illumination across the field of view
• Constant voltage drive at DC24V/500mA ensures stable light output without flicker
• White light color improves contrast and detail visibility on reflective surfaces
• 20,000-hour rated lifetime reduces replacement frequency and maintenance cost
• Working distance range of 40mm to 120mm accommodates various microscope head and sample heights
• Compact 90mm O.D. x 35mm I.D. x 33mm H design fits standard microscope mounting interfaces
• Ring light configuration eliminates shadows and hotspots from direct overhead illumination

Application Scenarios

• Inspection of polished metal surfaces, solder joints, and circuit board traces under polarized light
• Observation of birefringent materials such as crystals, plastics, and stress patterns in glass
• Use in metallurgical and quality control labs where surface defects must be detected under uniform lighting
• Support for polarizing microscopes during mineralogical or gemmological analysis
• Integration into a digital microscope setup to enhance image clarity for documentation

Who It Is For

• Metallurgy and foundry quality control labs inspecting surface integrity
• Jewellery and gemmology labs analyzing internal stress and crystal structure
• Electronics manufacturers performing PCB and SMD inspection under polarized light
• Research labs conducting birefringence or stress analysis on materials
• University teaching labs demonstrating optical polarization effects

Problems It Solves

• Non-uniform illumination from standard ring lights causes shadows and uneven brightness on reflective surfaces
• Lack of polarization in lighting leads to glare and reduced contrast in high-reflectivity samples
• Short LED lifetime in low-quality ring lights increases downtime and replacement costs
• Incompatible mounting dimensions prevent secure attachment to microscope heads
• Fixed working distance limits adaptability when changing sample height or objective focus

Technical Features

• 16 polarized LED elements arranged in a circular ring for even illumination
• Constant voltage drive at DC24V/500mA ensures consistent light output
• White light color for high contrast and natural color rendering
• Rated lifetime of approximately 20,000 hours under continuous operation
• Working distance range of 40mm to 120mm from the light plane to the sample surface
• Outer diameter: 90mm, inner diameter: 35mm, height: 33mm
• Mounting frame designed for compatibility with standard microscope head interfaces

Comparison With Other Options

Use Guide

• Ensure the microscope head has a compatible mounting interface before installation
• Connect the ring light to a DC24V/500mA power supply; do not exceed the rated voltage
• Position the light so the working distance to the sample is within 40mm to 120mm
• Align the polarizing filter with the microscope's polarizer for optimal contrast
• Clean the diffuser lens with a soft cloth to maintain light transmission and uniformity
