Base
Ocular lens
Located in the eyepiece, and usual magnification is 10x
Objective lens
Located above the stage, and typically has multiple stages of magnification
What are the objective lenses on our microscopes?
4x (red line), 10x (yellow line), 40x (blue line), 100x (white line)
What is the 4x?
Scanning objective lens
What is the 10x?
Low power objective lens
What is the 40x?
High dry objective lens
What is the 100x?
Oil immersion objective lens
Eyepiece
Portion of the microscope you look in
Eye guard(s)
Located on the eyepiece; reduces ambient light and glare; provides comfort and maximum visual effectiveness; assures proper eye to lens positioning
Diopter adjustment
Adjusts focus to compensate for the visual differences between your eyes
How is total magnification calculated?
Multiply objective lens power by ocular lens power
Stage
Where the slide is placed
Stage control
Moves stage front to back and side to side
Stage clips
Holds slide on the stage
Coarse adjustment
Moves stage up and down in large movements; do not use for objective lenses above 10x (4x and 10x only)
Fine adjustment
To fine tune view and look through the layers of the object in view
What should you always do when viewing through a microscope?
Keep your hand on the fine adjustment
Light source/illumination
Illuminates the slide
Condenser/aperture (iris) diaphragms
Adjusts brightness of light source/illumination (typically need higher brightness for higher magnification); Concentrates light with uniform intensity over the entire view-field
How do objects viewed in a microscope appear?
Reversed and upside down
What are the steps for putting away the microscope?
Turn light off, move 4x objective into place, lower stage completely, remove slide, clean oil immersion lens if necessary, cover with dust cover
What do you use to clean the microscope lenses?
Lens paper
