ML7000 Series Metallurgical Microscope Instruction Manual

[12] Now adjust the aperture iris (using lever (c) on the incident illuminator), closing it down slowly while observ-

ing the field of view. A point will be reached where there is a sudden distinct drop in brightness of field of view. 

When this occurs, open up the iris slightly, just until the brightness condition reverses, but no more.

[13] This procedure should be followed each time objectives are changed.

[14] The tension control knob is provided to allow the individial user to adjust the focus tension to his/her own 
preference. Tension may be increased by turning the knob with a counterclockwise motion. A lighter tension 
may be set by turning clockwise.

POLARIZING FACILITY

Polarizer

The Polarizing filter with mount 

 is used by inserting in one of the filter 

 slots on the vertical illuminator 

when polarizing microscopy is required.

Slide-in Analyzer

The Analyzer 

 is mounted in an in-tube slider which moves the analyzer in and out of the optical path and 

rotates between 0° and 90° by the lever 

. When “in” and at 45 ° position, and with the polarizing filter in 

the filter slot, these elements are said to be “crossed” and the field of view is said to be “extinguished”. In this 
condition the field of view is dark - except for optically active elements in the field, which rotate the angle of 

polarization and thus become visible against a dark background
