Comparison With Other Options
| Standard halogen ring light | The AM-168-90 uses LEDs with lower heat output and longer life, reducing thermal drift and bulb replacement frequency |
|---|---|
| Single-color LED ring light | The AM-168-90 supports multiple light colors with correct voltage outputs, allowing for specialized inspection tasks |
| Fixed-brightness LED ring light | The AM-168-90 offers continuous brightness adjustment, enabling real-time adaptation to sample reflectivity |
Use Guide
- Ensure the microscope ring mount has an inner diameter of 90-100mm before installation
- Connect the power supply to AC90-240V; verify the correct output voltage for the selected light color
- Adjust brightness continuously to match sample reflectivity and reduce eye strain
- Use red or yellow light with 8-9V output for non-white illumination tasks
- Avoid prolonged exposure to high brightness to extend LED lifespan
