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

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

The 8, 9, 10, 11, 12, 13mm coaxial LED ring light source is designed for microscope illumination in clinical, biomedical, and electronics inspection applications. It features a 5W LED with adjustable brightness from 0–100%, operates on AC90V–240V input, and delivers up to 240lux at 15mm effective light distance. The lamp head is 8mm in diameter with an aluminum alloy body and black finish, and it includes a plastic power box (110×60×30mm).

  • Coaxial design ensures even illumination directly on the sample without shadowing
  • Adjustable brightness from 0–100% allows control for different sample contrast and sensitivity
  • Wide input voltage (AC90V–240V) supports global use without voltage converters
  • 30,000-hour LED life reduces replacement frequency and maintenance cost
  • Compact 8mm lamp head fits standard microscope ports with minimal space intrusion
