3. Always allow adequate clearance at the rear of the X-Cite unit and microscope to
prevent excessive bending and/or crushing of the light guide against walls.
Minimum bend radius to prevent immediate damage to the LLG is 40mm,
however, a bend radius of at least 75mm is recommended for a light guide while
“in use”. Sharper bends can cause heat to build up and cause problems longer
term.
4. Always place the X-Cite unit close enough to the microscope so that there is
some slack in the light guide and no sharp bends.
5. Never leave an endcap on the output end of the light guide when the other end is
connected to the X-Cite unit; if the unit is turned on in this condition, the cap will
overheat, melt and/or permanently discolour the quartz end of the light guide.
6. Do not expose the light guide to extreme temperatures (above 35°C, below -5°C)
for extended periods of time during use, transport or storage; this may cause
degradation of the seals and allow air bubbles to form in the liquid.
What does a bubble look like?
Depending on the size and location in the light guide, a bubble may or may not be
obvious. To check for bubbles:
1. Disconnect the LLG from the X-Cite and microscope adapter.
2. Hold one end towards a bright window or overhead room light - DO NOT use an
X-Cite or any other focused light source for this test!
