Light-Guides

CoolLED's pE-1 and pE-2 systems use liquid light-guides to deliver the LED light from the Main Unit to the collimator fitted on the microscope.  2 off 1m light-guides are provided as standard with a system.  Alternatively, 3m light-guides can be used if there is limited space around the microscope or to keep heat, vibration or electro-magnetic radiation away from samples.

As the LEDs are only producing a narrowband of light during "on" times, the life expectancy of the light-guides is expected to exceed the warranty period significantly.  This is due to the reduced amount of energy being delivered compared to broadband sources which are often left "on" all day.
