Customization Options
- Available in two inner diameters: 61mm (AM-144-61) and 72mm (AM-144-72)
- Standard metal lamp holder; no alternative materials offered
- No options for different LED brightness, color temperature, or number of LEDs
Comparison With Other Options
| Plastic LED ring light | The metal lamp holder provides better heat dissipation and mechanical stability than plastic, reducing warping and extending lifespan under continuous use. |
|---|---|
| Fixed-brightness LED ring light | This model offers continuous brightness adjustment from 10% to 100%, allowing fine-tuning for different sample types and magnifications. |
| Single-diameter ring light | The AM-144-72 is available in both 61mm and 72mm inner diameters, so it fits multiple microscope head sizes without requiring adapters. |
Use Guide
- Confirm the inner diameter of your microscope head matches either 61mm or 72mm before mounting
- Connect the ring light to an AC90-240V power source; ensure the voltage matches your local supply
- Adjust the brightness using the control dial to suit the sample and magnification level
- Position the ring light so the working distance is within 40-160mm for optimal illumination
- Avoid placing the ring light in high-temperature environments that may affect the LED lifespan
