Changing Magnification

 

 

a. 

Magnification is changed by rotating the nosepiece until a different lens is moved into the  

 

 

 

optical path.  Always turn the turret until you hear it  “click”.  This indicates that the lens is  

   properly 

positioned. 

  

 

 

b. 

The standard lenses that are provided with your microscope are a widefield 10x eyepiece  

 

 

 

(HS1+1, HS-1D Models come with 2 separate eyetubes as well as 2 eyepieces). 4x, 10x and  

 

 

 

40x objectives.  The 40x objective has a special spring retractable mechanism which    

 

 

 

retracts slightly when front of lens comes in contact with the specimen slide.  See chart  

 

 

 

below for specifications on objectives: 

OBJECTIVE SPECIFICATION CHART

 

 

c. 

Also note that each objective has a color ring.  This allows you to quickly change in  

 

 

 

 

magnification by referring to an easily observed color rather than to a number.

 

 

d. 

The microscope has been parfocalled at the factory, which allows the user to easily change  

 

 

 

from one magnification to another requiring little or no adjustment of the fine focus    

   knobs.

 

 

e. 

As you increase the magnification, the field of view (area of specimen seen through the  

 

 

 

microscope) will decrease.  That is why it is easier to find the specific area of interest on the  

 

 

 

specimen by starting with the lowest 4x objective lens , before increasing magnification  

 

 

 

with the 10x or 40x objective lens.

  f. 

 

NOTE: 

Care must be taken when rotating the 40x objective lens into place.  This lens has  

 

 

 

a spring retractable mechanism which retracts slightly into its housing if the front of the  

 

 

 

lens strikes the specimen slide.  With fine focus adjustment at mid-range, the rack stop has  

 

 

 

been adjusted at the factory to assure the 40x lens will clear the thickness of a normal    

 

 

 

specimen slide and cover slip.  However, if the rack stop has been improperly adjusted, or 

 

 

 

if you are using a thicker than 0.17mm cover slip, moving the 40x lens too quickly could  

 

 

 

cause damage to the front lens element or to the slide.
