OPERATION 

(continued)

 
 

Aperture Diaphragm Adjustment  

The aperture size is increased or decreased by rotating the condenser aperture diaphragm lever.  When 
the aperture is closed the brightness and resolution are decreased but the contrast and range of focus 
are increased.  If the aperture diaphragm is opened, the brightness and resolution are increased; 
however the contrast and range of focus are diminished.  For optimal viewing conditions set the 
condenser aperture diaphragm lever to match the magnification of the objective in the optical path. 

 
 

Using Oil Immersion  

The procedure for examining a specimen using an oil immersion objective is as follows: 

1.  Rotate the nosepiece so the low power objective is in the optical path. 

2.  Place one drop of immersion oil on the lighted area of the specimen slide.  Dust or air bubbles in 

the oil can destroy the definition of the image.  If the bubbles are trapped between the objective 
lens and the slide, clean off the oil and start again or try to eliminate the bubble by rotating the 
objective back and forth.  

3.  Rotate the nosepiece so the 100xR oil immersion objective is in the light path. 

4.  With your eye at the level of the stage, use the coarse focus knob to raise the stage with the 

specimen cover glass.  When you see a flash of light at this location the objective lens has made 
contact with the immersion oil and the microscope can now be focused using the fine focus knob. 

5.  Each time you finish using the oil immersion objective wipe off all traces of oil from the objective 

and the specimen cover glass with a lens tissue or clean soft cloth.  Cleaning after each use will 
prevent oil from contaminating the high dry objective (40xR) and deforming its optical 
performance, prevent dust and dirt from accumulating on the lens of the objective and degrading 
its optical performance and will keep the slide clean to work with.  

 

 

Focus Stop  

The focus stop on the ACCU-SCOPE 3012-LED Series is built-in for ease of use and is pre-adjusted by 
our factory technicians.   

 
 

Lamp Replacement 

The LED lamp is rated for 20,000 hours and should last for many years under normal use.  However, 
should your lamp need replacing, please contact an authorized ACCU-SCOPE service center or call 
ACCU-SCOPE at 1-888-289-2228 for an authorized service center near you. 

 

Replacement Bulb: Catalog #12-3259 (5 watt LED with heat sink)
