- Illuminator
- Condenser
- Iris Diaphragm
- Eyepiece
- Index
- Diopter Adjustment Knob
- Coarse Adjustment Knob
- Fine Adjustment Knob
- Upper Vertical Knob
- Lower Vertical Knob
- Stage
- Stage Clip
- Revolving Nosepiece
adjusts the light
INTENSITY KNOB
light source
ILLUMINATOR
concentrates the light that is coming from the light source
CONDENSER
allows you to adjust the light passing through the condenser
IRIS DIAPHRAGM
also known as an ocular lens - has a 10x magnification
EYEPIECE
located between the two lenses - is adjusted so you can see the “convergent image”
INDEX
for people with glasses
DIOPTER ADJUSTMENT KNOB
moves the stage up (clockwise) and down (counterclockwise)
COARSE ADJUSTMENT KNOB
allows rapid focusing of the specimen
COARSE ADJUSTMENT KNOB
moves the stage up and down but not drastically and sharpens the image
FINE ADJUSTMENT KNOB
moves the stage clip vertically and useful for doing the zigzag motion
UPPER VERTICAL KNOB
moves the slide horizontally and useful for doing the zigzag motion
LOWER VERTICAL KNOB
where the slide is placed
STAGE
holds the specimen slide in place
STAGE CLIP
holds all the lens
REVOLVING NOSEPIECE
- color: red
- has a magnification of 4x
- shift to this lens after using
SCANNER
- color: yellow
- has a magnification of 10x
LOW POWER OBJECTIVE
- color: blue
- has a magnification of 40x
HIGH POWER OBJECTIVE
- color: black and white
- has a magnification of 100x
- uses cedar wood/tree oil
OIL IMMERSION OBJECTIVE
kind of light used in parasitology for fresh specimens
SUBDUED LIGHT
used for stained specimens
BRIGHT LIGHT
the single image that can be seen by your left and right eye
CONVERGENT IMAGE
you must hear or feel this so you know that the lens has been adjusted
