8.8 Light Sources
• The brightness is set using the function keys
(73.5). Then, the
INT
function keys are as-
signed to the currently active axis for trans-
mitted light (TL) or incident light (IL).
• For TL and IL:
Settings can be made either in large or small
increments. Pushing both
INT
buttons simulta-
neously switches between coarse and fine
setting. The display on the Leica SmartTouch,
menu page ‘Light’ (fig. 74), changes accord-
ingly.
Coarse adjustment:
0-20
Fine adjustment:
0-255
• The light intensity is set and stored individu-
ally for each objective and each contrast
method.
• For FLUO: The brightness is set in 5 fixed steps
100% / 55% / 30% / 17% / 10%
