Microscope Instructions. 1. Carry microscope with 2 hands always! One to support the base and the other on the arm. 2. Plug microscope in to power outlet.

1. Refer to DIN# for magnification 2 3 With stage all the way down, place slide with specimen on stage centered over the hole in the stage. 4.

SCIENTIFIC TOOLS. Microscopes Light Microscope – (optical microscope) – Uses light to produce an enlarged view of a specimen. Magnification – Magnifying.

General Information Used to magnify thin specimens Light must be able to pass through the object Knowing the basic parts will help you better use this.

MICROSCOPE PARTS.

1. Eyepiece – 10x magnification Rotates to move pointer 2. Body Tube – carries image to ocular lens in eyepiece.

Microscope: Used to study items too small to be seen with the unaided “naked” eye Compound light microscope: Uses light to form enlarged image of a specimen.

Introduction to the Microscope Lab

Common Microscope Types Compound Monocular Dissecting

Microscope Type Uses Compound Light: Dissection: Used to examine materials mounted on microscope slides (usually sectioned & stained) Generally provides total magnification from 40X to 1000X Does not provide space for dissection of materials being examined. Dissection: Used to examine thick materials on microscope slides & whole specimens living or preserved Generally provides total magnification from 10X to 45X Provides space between stage & objectives for dissection.

Compound Light Microscope Parts & Functions Eyepiece: The part of the microscope you look into Magnifies material being viewed by 10X Sometimes contains a pointer that can be seen as you look into the eyepiece. Also be called the ocular.

Microscope Parts & Functions Nose piece: Part of microscope to which the objectives are attached Rotates to allow for the changing of objectives to increase or decrease magnification.

Microscope Parts & Functions Arm: Where the nosepiece is attached Hold the microscope by this when carrying. Always use both hands!

Microscope Parts & Functions Objectives: Magnify material being examined Scanning objective magnifies 4X (40x) Medium Objective. magnifies 10X (100X) High Powered Obj. magnifies 40X (400x) Total magnification = Eyepiece Mag. X Objective Mag.

Microscope Parts & Functions Stage: Platform on which microscope slide rests Stage clips: Secures slide to the mechanical stage Be careful – if allowed to snap down, they break slides!

Microscope Parts & Functions Coarse adjustment knob: Coarse focusing Used to find specimen, but with less detail. Fine adjustment knob: Precise focusing Small turns make big changes. * Remember – Specimens are 3-Dimensional and focusing adjusts the level you look at.

Microscope Parts & Functions Diaphragm: regulates the amount of light passing through the specimen When viewing translucent specimens, use small opening. When viewing opaque specimens us large opening.

Microscope Parts & Functions Illuminator Light source On/Off switch is on base Base: provides support for microscope

Microscope Storage Always with one hand on the arm & one on the base. Microscope Cabinet Always with one hand on the arm & one on the base.

Preparation for Storage Make sure no slides are on the stage Lower stage for maximum distance between objective & stage Wrap cord around base (clockwise)

Preparation for Use Transport microscope to work station Plug in microscope Inspect and clean microscope
