General Flashcards
Is a coordinate system of lenses arranged to produce an enlarged, focusable image of a specimen
Light microscope
Magnifies a specimen, meaning that it increases its apparent size.
Light microscope
A light microscope has two or sometimes three systems. What are those?
An illuminating system
An imaging system
A viewing and recording system
Which Concentrates light on the specimen, usually consists of a light source, condenser lens and iris diaphragm
Illuminating system
It is a lightbulb located at the base of the microscope and it illuminates the specimen by passing through a thin, almost transparent part of the specimen.
Light source
It is located immediately below the specimen, focuses light from the light source onto the specimen
Condenser lens
It is a krurled ring or level that can be opened and close to regulate the amount of light reaching the specimen
Iris diaphragm
Improves resolution and magnifies the image
Image system
What are the 4 objectives in the microscope
Low magnification 4x
Medium magnification 10x
High magnification 40x
Oil immersion 100x
Microscope with one ocular are?
Monocular microscope
Microscope with two ocular is?
Binocular microscope
Ocular usually magnify the image up to?
10x
If present, converts radiation to a viewable and/or permanent image
Viewing and recording system
What type of oil is used exclusively with certain microscopes to enhance image clarity?
Immersion oil
What is the substance used to kill and preserve a specimen before it is examined?
Fixing fluid
