Because of their high optical quality, the
WILD M7A and M7S Stereomicroscopes
are particularly suitable for precise measure-
ments.
The M7S is to be used preferably in the ver-
tical-beam position (see section 2.1). If mea-
surements are carried out with the right eye,
e.g. with the measuring eyepiece of the
Digital Length-Measuring Set, the binocular
tube can be rotated 180° (see section 3).
Depending on the outfit, request a shorter for
the incident- or transmitted-light Stands if
necessary.
For measurement work, adjustable WILD
eyepieces can be furnished with a graticule
(reticle) in mount (see section 5).
The graticules available have various scales
or grids, or a crosshair.
Angles can be measured with the 10 x wide-
field goniometer eyepiece, or with the
rotating stage used for Polarisation work.
Carriers are available for Leitz measuring
stages(fig. 2).
Further details of procedures used for mea-
suring are given in the Instruction booklet
M2 275.
The WILD M M S 2 3 5 Digital Length-Mea-
suring Set (fig. 1) (with printer) streamlines
and accelerates the action of measuring.
The determinations of the calibration values
and of the measurement data are micropro-
cessor-controlled. After a Single calibration
procedure for each magnification, the length
of the feature is constantly visible on a digital
display.
Calculation errors arid check measurements
aresuperfluous.
Detailed information is to be found in the
Instruction booklet M2 270.
