Axial observation
Aperture
The
Shift the stereomicroscope to the left or the right position. The object is now located directly beneath either the left or the right beam path.
• When photographing or measuring, se- lect the beam path above which the pho- totube or measuring graticule is located.
A rotating aperture is build into the AX microscope carrier. It prevents interfering reflections during axial observation with coaxial incident illuminator and
•With the AX microscope carrier for MS5, MZ6, MZ75, MZ95, the aperture automatically turns during the moving process.
•With the AX microscope carrier for MZ125, MZ16, MZ16 A, the aperture is located underneath the microscope carrier and must manually be turned as follows:
Please note:
– In the position for stereoscopic observa-
tion through both beam paths, turn the aperture counterclockwise until it stops. Otherwise the field of view is underex- posed (vignetting).
– In the position for axial observation through the right or left beam path, turn the aperture clockwise until it stops.
