·
The working distances of the 110ALK0.3X and 0.4X can be varied according to the system.
The indicated magnifications (0.3X and 0.4X) are the values when the working distances are 350 mm
and 240 mm respectively.
·
The 110AL2X-2 cannot be combined with the optional SZ2-LGR ring light guide illumination system.
· The working distance is constant regardless of the zoom magnification.
· The total power and actual field can be calculated with the following formulae.
Total power = Zoom magnification x Eyepiece magnification x Auxiliary objective magnification*
Actual field =
Eyepiece FN
Zoom magnification x Auxiliary objective magnification*
* This value is 1X when the auxiliary objective is not used.
NOTE
TIP
The following data shows only the typical magnifications of each zoom magnification.
