Powered by the Dolan-Jenner Fiber-Lite MI 150 Illuminator, this fiber optic ring light system provides 350,000 foot candles of high-intensity, cold light illumination and a lamp color temperature of 3400K. The power source receptacle accepts the included ring light cable and any fiber optic cable with a 15mm end tip diameter. The 36-inch flexible fiber-optic cable allows for convenient placement of the lamp housing and the 60mm ring diameter fits a wide range of stereo microscopes. A variable-intensity controller offers illumination from zero to full brightness or any setting in between, making it ideal for a wide range of industrial applications and photo documentation requirements. The illuminator is UL, CE and C-Ul certified with 0-100% variable intensity. Please note that the ring light requires a Barlow lens or ring light adapter for use with Omano microscopes.
