108pcs 41mm LED Ring Light Stereo Microscope AM-108-41

The 108pcs LED ring light AM-108-41 is a 41mm diameter illumination accessory designed for stereo microscopes.

Product Overview

The 108pcs LED ring light AM-108-41 is a 41mm diameter illumination accessory designed for stereo microscopes. It provides 80,000 LUX of uniform white light at 6500-8000K color temperature, with a continuous 10-100% brightness adjustment. The light is mounted on a 12V constant current drive with over-temperature and short-circuit protection, ensuring stable operation during long inspection sessions. It fits microscopes with a 41mm inner diameter optical path and supports working distances from 50mm to 300mm.

  • Teaching laboratories in engineering and electronics programs
  • Quality control teams documenting inspection results with consistent lighting
  • Micro-assembly and repair benches where shadow-free illumination improves accuracy

Problems It Solves

  • Uneven or dim lighting causes shadows and glare, making defect detection difficult
  • Fixed brightness lights force operators to use external filters or reduce magnification
  • Poor heat dissipation in plastic housings leads to LED degradation and color shift
  • Lack of over-current protection risks damage to the microscope's optical path
  • Inconsistent color temperature distorts material appearance during inspection

Technical Features

Use Guide

  • Ensure the microscope's optical path has a 41mm inner diameter before mounting
  • Connect the power supply to AC110V-240V; the output is 12V DC
  • Adjust brightness from 10% to 100% based on sample reflectivity and ambient light
  • Do not cover the light ring during operation to avoid overheating
  • Use with a stereo microscope to maintain consistent working distance between 50mm and 300mm
  • Verify the light ring is securely mounted before use to prevent misalignment
Answers

Frequently Asked Questions
