What are the 3 main lens systems of the microscope?

Types of Lenses

• Objective lens. The objective lens consists of several lenses to magnify an object and project a larger image.
• Ocular lens (eyepiece) A lens to be mounted on the observer side.
• Condenser lens. A lens to be mounted under the stage.
• About magnification.

What are the 3 groups of the parts of a microscope?

The three basic, structural components of a compound microscope are the head, base and arm.

What are the three elements that control the light reflecting through the microscope?

The intensity of illumination and orientation of light pathways throughout the microscope can be controlled with strategically placed diaphragms, mirrors, prisms, beam splitters, and other optical elements to achieve the desired degree of brightness and contrast in the specimen.

What is the lens in the eyepiece called?

The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object.

What are the three types of objective lenses?

Most compound microscopes come with interchangeable lenses known as objective lenses. Objective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power, and (typically) oil immersion objectives, respectively.

What are the three main parts of a microscope?

Figure: Diagram of parts of a microscope There are three structural parts of the microscope i.e. head, base, and arm. Head – This is also known as the body, it carries the optical parts in the upper part of the microscope. Base – It acts as microscopes support.

What kind of lenses are used in compound microscope?

There are two optical systems in a compound microscope: Eyepiece Lenses and Objective Lenses: Eyepiece or Ocular is what you look through at the top of the microscope. Typically, standard eyepieces have a magnifying power of 10x.

What makes up the optical train of a microscope?

Together, the optical and mechanical components of the microscope, including the mounted specimen on a glass micro slide and coverslip, form an optical train with a central axis that traverses the microscope stand and body.

How are the objectives arranged in a standard microscope?

In standard microscopes, the objectives are mounted such that when you switch between objectives, the sample remains in focus. Objectives arranged in this way are described as parfocal. The second, the eyepiece, also referred to as the ocular, has several lenses which slide inside a cylindrical barrel.
