Problem Cause 

Solution 

No image. 

Nosepiece badly 

positioned. 

Turn, until it clicks into 

position. 

Image too bright. 

Reduce light intensity. 

Poor resolution. 

Objective lens dirty. 

Clean objective. 

Eyepiece lens dirty. 

Clean eyepiece. 

Specimen slide up 

side down. 

Place slide with slip  

facing up. 

Cover slip on specimen 

slides wrong thickness. 

Use 0.17mm thick cover 

slip. 

Light too bright. 

Reduce light intensity or 

adjust diaphragm 

aperture. 

Condenser dirty. 

Clean condenser. 

Spots in field  

of view 

Dirty eyepiece. 

Clean eyepiece. 

Dirty slide. 

Clean slide. 

Dirty condenser. 

Clean condenser. 

Uneven illumination 

 of field 

Nosepiece not properly 

positioned. 

Turn until clicks into 

position.
