Histo LAB

The lens at the top that you look through, usually 10x or 15x power.

Allow you to make minor corrections to the image, compensating for the difference in vision between the two eyes.

It contains the optical parts in the upper part of the microscope

Contains the objective lenses; rotates to allow the user to switch between different objective lenses.

Three are 3 or 4 objective lenses on a microscope. The objective lenses almost always consist of 4x, 10x, 40x and 100x powers. The most common eyepiece lens is 10x and when it coupled with others, total magnification is 40x (4x times 10x), 100x , 400x and 1000x. Objectives can be forward or rear-facing.

It supports the tube and connects it to the base.

The stage of a microscope is a flat platform where you place your subject slides. Stage clips hold the slides in place. The mechanical stage of your microscope will help you to move the slide around by turning two knobs. One knob moves it left and right, the other knobs move it up and down.

Large knob used for focusing the image under low power (general focusing)

Smaller knob used for focusing the image with the medium- and high-power objectives (fine-tuning)

It is the hole in the stage through which the base (transmitted) light reaches the stage.

Most of the laboratory microscopes have a rotating disk under the stage known as _________ it controls the amount of light reaching the specimen. The Iris Diaphragm is located above the condenser lens and below the microscope stage.

It is used to collect and focus the light from the illuminator on to the specimen.

Is the most important microscope parts and it serve as light source for a microscope during slide specimen visualization. It is a continuous source of light (110 volts) used in place of a mirror. The mirror of microscope is used to reflect light from the external light source up through the bottom of the stage. Usually, the Illuminator located in the base of the microscope. Most light microscopes use low voltage, halogen bulbs with continuous variable lighting control located within the base.

These allow you to move your slide while you are viewing it, but only if the slide is properly clipped in with the stage clips.

The bottom of the microscope, used for support.

It adjusts the intensity of the light passing through the microscope

This switch on the base of the microscope turns the illuminator off and on.

Are used to look at a variety of samples that you would be able to hold in your hand. A _______ provides a 3D image or "______" image and typically will provide magnification between 10x - 40x.

May also be referred to as a biological microscope. ____________microscopes are used in laboratories, schools, wastewater treatment plants, veterinary offices, and for histology and pathology

This microscopes are available as biological _____________microscopes or metallurgical ________ microscopes. Biological _______ microscopes provide magnification of 40x, 100x and sometimes 200x and 400x. These biological _________ microscopes are used to view living samples that are in a petri dish. An ____________ microscope allows the user to place the petri dish on a flat stage, with the objective lenses housed beneath the stage.

Are high power microscopes designed to view samples that do not allow light to pass through them. Reflected light shines down through the objective lenses providing magnification of 50x, 100x, 200x, and sometimes 500x.

Use polarized light along with transmitted and, or reflected illumination to examine chemicals, rocks, and minerals. ________ microscopes are utilized by geologists, petrologists, chemists, and the pharmaceutical industry daily
