AL ERG (ERGO) Auxiliary Objective
Using the AL ERG auxiliary objective allows
you to continuously change the eye level
through a 40 mm range.
1
Rotate the milled ring on the AL ERG to
attach it to the zooming body.
2 Rotate the focus knobs on the focusing
stand to raise or lower the zooming
body to set to the height best suited for
viewing.
3 Rotate the rotation barrel to focus on the
sample.
4
To change the eye level more, rotate the
rotation barrel referring to the eye level
scale and focus on the sample using the
focus knobs. One graduation of the eye
level scale is equivalent to 10 mm of the
eye level. The upper the scale, the
higher the eye level.
Note) Changing the eye level will change the magnification. The
magnification is 0.77X at the highest eye level, and 1.06X at the
lowest eye level. To know the exact magnification, calculate it
using the reticle with scaled cross hairs, etc.
