IMPORTANT:

 The working distances of the 40XRD and 100XRD objectives 

to the slide surface are very small and although the oil immersion 
objectives are sealed to prevent oil contamination, it is a good practice 
to avoid dragging these objectives through an oiled slide. The 100XRD oil 
immersion lens on Swift microscopes has a spring-loaded end to prevent 
cracking the cover slip upon its initial contact. Once this zone of safety is 
exceeded by moving the slide further toward the lens, a point can be 
reached where damage will occur. Always make a practice of frequently 
checking the position of the lens on the slide. Note that a 100XRD 
objective requires an iris diaphragm for brightfield oil immersion 
microscopy. 
 
 
 
 
 
 
 

 

 

 

HOW TO USE THE POINTMASTER

® 

EYEPIECE RETICLE 

 

Swift's patented POINTMASTER® eyepiece reticle, which is installed in 
the eyepiece of the M3500 microscope, enables the user to easily 
measure the size of the specimen. 
 
I.  The numbers on the chart indicate the actual size of the  
  

POINTMASTER® scale in millimeters. For example, the length is 

  

1.0mm from the top of the arrow to the bottom; the total length of 

  

the scale is 8.0mm, etc. The thickness of all the horizontal lines is 

  

0.01mm. 

 
2.  To obtain the actual physical size of a specimen, divide the 

POINTMASTER® scale readings by the magnification of the objective 
lens that is in use. Divide the readings by 10 if the 10X objective is 
being used, 40 if the 40XRD objective is in use, or 100 if of 100XRD is 
in use.
