What are the objective lenses attached to?
The lenses are attached to the nosepiece. Usually a compound microscope has four objective lenses: scanning (4x) low-power (10x) high-power (40x) and oil immersion (100x) lenses.
What holds the eyepiece and objective lens?
Head: The upper part of the microscope houses the eyepiece and objective lenses. Tube: Where the eyepieces are dropped in. Also, it connects the eyepieces to the objective lenses. Stage: The flat platform that supports the slides.
Which part of the microscope objective lenses attach?
Monocular or Binocular Head: Structural support that holds & connects the eyepieces to the objective lenses. Arm: Supports the microscope head and attaches it to the base. Nosepiece: Holds the objective lenses & attaches them to the microscope head. This part rotates to change which objective lens is active.
What holds the three objective lenses?
Nosepiece or Turret: holds the objective lenses and can be rotated easily to change magnification.
What is the slide holder on a microscope?
Slide holder – the mechanical device that is used for holding the slide in place so that it can be moved with ease from side to side back and forth. Stage opening – part of the mechanical stage that allows light to pass through the specimen for a better view.
What is a microscope arm?
Arm: The part of the microscope that connects the eyepiece tube to the base. Articulated Arm: Part of a boom microscope stand, an articulated arm has one or more joints to enable a greater variety of movement of the microscope head and, as a result, more versatile range of viewing options.
Which two parts are used to hold the microscope?
The three basic, structural components of a compound microscope are the head, base and arm. Arm connects to the base and supports the microscope head. It is also used to carry the microscope.
What is the iris diaphragm on a microscope?
Microscope Anatomy & Function. Condenser. Page 4 of 4. The condenser has an iris diaphragm that controls the angle of the beam of light focused onto the specimen. The iris diaphram is an adjustable shutter which allows you to adjust the amount of light passing through the condenser.
What is the diaphragm on a microscope?
Student compound biological microscopes have either an iris diaphragm or a disc diaphragm beneath the stage. The diaphragm controls the amount of light that is allowed to pass through the microscope stage and up toward the objective lens and ultimately the eyepiece.
What is the name of the part of the microscope that holds the objective lens in position and can change which objective to use?
Revolving Nosepiece or Turret Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power.
What is a slide holder?
Containers such as slide boxes, trays, mailers, and carriers used to safely store and transport microscope slides; available in a variety of materials including cardboard, plastic, and stainless steel.
What holds the slide in place?
Stage clips Stage clips hold the slides in place. Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power.
What is used to hold a slide in place on the stage?
Spring loaded metal clips on the microscope stage are used to hold the slide in place.
Which part is used to hold the microscope in transferring from one place to another?
The microscope arm connects the eyepiece tube to the base. This is the part you should hold when transporting a microscope.
Is condenser and diaphragm the same?
Condenser is used to collect and focus the light from the illuminator on to the specimen. It is located under the stage often in conjunction with an iris diaphragm. Iris Diaphragm controls the amount of light reaching the specimen. It is located above the condenser and below the stage.
What is a disc diaphragm?
The disc diaphragm is used to vary both the intensity and size of the cone of light that is projected upward into the prepared slide. There is no set rule regarding which setting should be used for a particular objective lens magnification.
What does the nosepiece do on a microscope?
Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power. Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4X, 10X, 40X and 100X powers.
What is the eyepiece of a microscope?
Eyepieces (Oculars) The eyepiece, or ocular lens, is the part of the microscope that magnifies the image produced by the microscope's objective so that it can be seen by the human eye. In this resource we will look at the different types of eyepieces, their components, how they work, and how to use them.
What are slide boxes?
Slide boxes are used to store, organize, and safely transport microscope slides. Available slide boxes can store between 25 to 100 slides and are configured with clasps to ensure secure closure.
What holds the slide in place on a microscope?
stage clips Use the stage clips to hold the slide in place.
How are slides held on the microscope?
In a dry mount, the simplest kind of mounting, the object is merely placed on the slide. A cover slip may be placed on top to protect the specimen and the microscope's objective and to keep the specimen still and pressed flat.
What does a diaphragm do on a microscope?
Opening and closing of the condenser aperture diaphragm controls the angle of the light cone reaching the specimen. The setting of the condenser's aperture diaphragm, along with the aperture of the objective, determines the realized numerical aperture of the microscope system.
What does a diaphragm and condenser do on a microscope?
The purpose of the condenser is to concentrate the light onto the specimen, its diaphragm regulates resolution, contrast and depth of field. Many modern course microscopes are equipped with a condenser and an associated condenser diaphragm.
What is a microscope diaphragm?
Student compound biological microscopes have either an iris diaphragm or a disc diaphragm beneath the stage. The diaphragm controls the amount of light that is allowed to pass through the microscope stage and up toward the objective lens and ultimately the eyepiece.

How are slides held in place?
Slides are held in place on the microscope's stage by slide clips, slide clamps or a cross-table which is used to achieve precise, remote movement of the slide upon the microscope's stage (such as in an automated/computer operated system, or where touching the slide with fingers is inappropriate either due to the risk …
