What is parfocal capability?
lenses: set up or arranged so that when one lens is changed for another, there is no change in focus. * Applied usually to turret mounted lenses e.g. on microscope; also in telescopes: ~ eyepieces: changing one for another does not require refocusing. * When the distance from the object to the rear principal plane of each lens is equal, they are said to be parfocal.
What property of a compound light microscope enables a person to change objectives without major focusing adjustments?
It's Parfocal property."Parfocal: This is a focus issue. When changing from one objective to another, the new image should be either in focus or close enough so that you can refocus with only minor adjustments. Most microscopes are parfocal." from www.microscope-microscope.org
Which microscope uses lenses and objectives to magnify?
An optical microscope uses lenses and objectives to magnify objects. Light passing through the lenses magnifies the image, allowing for detailed viewing of small specimens.
Why is the microscope called a compound microscope?
The compound microscope is called compound because the modifier compound means "two or more." A compound microscope has two or more lenses lenses. This is to be distinguished from a simple microscope which has one lens. Such a microscope is structurally equivalent to a magnifying glass, though not necessarily a hand held lens.
Why is a light microscope also called a compound microscope?
A light microscope is called a compound microscope because it uses multiple lenses (a compound of lenses) to magnify the image of a specimen. This allows for higher magnification and resolution compared to a simple microscope.
What is the advantage of the parfocal lenses?
The advantage of a parfocal microscope=when different objective lenses are rotated, the object being examined will remain in view
What does it mean if your microscope is parcentric?
If a microscope is parcentric, it means that as you switch between different objective lenses, the specimen will remain centered in the field of view without having to readjust its position. This ensures that the specimen stays in focus and properly aligned as you change magnifications.
What is a Term used to describe the feature of microscope that makes it possible to move among the objectives lenses with just minor focusing?
Parfocal.
Parts of magnifying system of a microscope?
the magnifyings system include the eye piece i.e. ocular lens and objective i.e. parfocal lenses
How to describe the feature of the microscope that makes it possible to move among the objective lenses with only minor focusing?
The feature on a microscope that allows you to switch between objective lenses with minimal focusing is called parfocal. This means that when you change from one objective lens to another, the specimen remains in focus and only requires minor adjustments to fine-tune the focus.

What is the function of of parrel in microscope?
The parfocal feature in a microscope allows for maintaining focus when switching between objective lenses without needing significant readjustment. This is achieved by aligning the focal planes of different objectives.

What term is used to describe the feature of microscope that makes it possible to move among objective lenses with just minor focusing?
Parfocal is the term used to describe the feature of a microscope that allows for switching between objective lenses with minimal or no need for refocusing. This is a convenient feature that helps maintain focus when switching between different magnifications.
What type of microscope has multiple lenses?
A compound microscope has multiple lenses
Where are the ocular lenses on a microscope?
The ocular lenses on a microscope are located at the top of the microscope's eyepiece tube. They are the lenses that you look through to view the magnified specimen on the microscope slide.
What instrument uses light and lenses is used to view cells?
An optical microscope uses light and one or more lenses to view cells. An optical microscope with two or more lenses is called a compound optical microscope.
