Microscope The Pieces and Parts

Body Tube #1 in picture Allows light from objectives to pass upward to form first image.

Eyepiece (ocular lens) # 9 on picture 10 x magnification of image

Revolving Nosepiece # 2 in picture Holds the 3 objectives Allows objectives to rotate into position (listen for the CLICK!)

Objectives Low Power: 4 x magnification (#3)also called “scanning” Medium:10 X magnification (#4) High:40x or 43x magnification (# 5)

Total Magnification Ocular lens x objective lens = total magnification Ex: Ocular x low power = 10 x 4= 40 x magnification Ocular x medium = 10 x 10= 100 x magnification Ocular x high power =10 x 40= 400 x magnification

Stage Clips and Stage # 6 clips # 11 stage Clips- holds specimen in place on stage stage- platform to hold the specimen on microscope

Diaphragm # 7 Regulates amount of light on the specimen. Ranges from 1 to 5 (1 smallest….to 5 largest)

Light Source, Arm, and Base # 8 light source # 10 arm # 14 base Light source: helps image show better (Can be light or mirror) Arm: used to carry microscope Base: used to support when carrying microscope

Course Adjustment Knob # 12 Larger knob on microscope Moves stage up and down Used for initial focus of specimen DO NOT USE ON HIGH POWER!!!!!!! (Or you will BREAK the slide!!!)

Fine Adjustment Knob # 13 Used to fine tune the image Makes sharper/clearer

BE READY FOR A QUIZ!!!! TOMORROW!! ***** You must pass to do the microscope lab…
