10 times eye piece 40 times objective lens?

What is the total magnifying power of low power objective lens?

What is the value of the smallest objective?If it is 4x,The total magnification = eye piece x objective lens= (10x) x (4x)= 40x

What is more powerful out of the Objective or the Eye piece lens?

The focal length of EyePiece is relatively larger to that of the Objective lens. Power of a lens is inversely proportional to it's focal length. Therefore, Objective is slightly more powerful than EyePiece.

What is the objective lens on a microscope?

An optical microscope used in a laboratory would have 3 different types of lenses.They are :-(1) Condenser lens- directs light to the specimen if there is no in built light source.(2) Eye piece - lens close to the eye of the observer which magnifies the image created by the objective lens.(3) Objective - These are the lenses which are positioned closest to the specimen mounted on the stage of the microscope which magnifies the specimen. There could be several objective lenses in an optical microscope, generally three. The low power objective (usually magnifies 4 times), mid power objective (usually magnifies 10 times) and the high power objective (usually magnifies 40 times).

What does the 10x on the medium power objective of a microscope mean?

The power of a microscope magnification is the eye piece power times the objective lens so 10X eye piece times 10X objective is 100 power Common eyepieces are 10x 15x, 20X. The limit is about 2000X in an excellent unit. Average practical use is about 1000X to 1400X In expensive scopes the higher power objective lenes as 100X are made from oil not glass.

What is the total magnification of a microscope with a 10x Eyepiece and a 40x Objective?

The total magnification of the microscope when using the 40x objective depends on the strength of the eye piece lens. Typically a 10x eye piece lens is used in college microscopes this would give 40x10 = 400x magnification.

Which part of an optical microscope contains the magnifying lens?

The body tube of a compound optical microscope contains two lens systems, the objective lens composed of one or several lenses that magnify the image of the object being examined, and the ocular lens at the eyepiece end. The magnification of the microscope depends on the focal lengths of the two lens systems.

What is the name of the lens closest to your eye in a microscope?

It's called an "OCULAR" according to a microscope supplier site.

Total magnification is determined by?

Total magnification is determined by multiplying the magnification of the objective lens by the magnification of the eyepiece. This formula is used to calculate the overall magnification of an image when viewed through a microscope.

Part of microscope that holds the objective lens?

The part of the microscope that holds the objective lens is called the nosepiece. It allows for easy changing of various objective lenses to adjust the magnification during observation. The nosepiece is typically located below the stage where the specimen is placed.

Parts of magnifying system of a microscope?

the magnifyings system include the eye piece i.e. ocular lens and objective i.e. parfocal lenses

What is does a eye piece of a microscope?

The eyepiece of a microscope is the part that you look through to view the specimen on the slide. It usually contains lenses that further magnify the image produced by the objective lens. The eyepiece typically has a standard magnification power of 10x.

Function of HPO in microscope?

The Word "HPO" in Microscope stands for High Power Objective.Most standard compound microscopes use a combination of an eye piece lens and objective lenses in order to magnify an object. In the majority of these microscopes, the eye piece lens will have a magnification factor of 10 x, or ten times the original size, and the objective lens system will consist of three lenses of varying focal lengths, described as low, medium and high power objective lenses.The magnification factors (MF) of the three objective lenses are usually as follows:Low Power Objective (LPO) Lens, MF = 4 xMedium Power Objective (MPO) Lens, MF = 10 xHigh Power Objective (HPO) Lens, MF = 40 xThe total magnification possible with a standard compound microscope is the multiple of the magnification factor of the eye piece lens and the objective lens in use. In other words, total magnification using the LPO lens would be 40 times the original size, the MPO lens would achieve a total magnification of 100 times, while the HPO lens will achieve a total magnification of 400 times the original size of the object to be viewed.The HPO lens is longer, and therefore closer to to the object viewed, resulting in a narrower field of vision, making it difficult to study living, fast moving organisms. It does, however, make it possible to see details which are not visible on lower magnification on non-living specimens or slow moving living organisms. The HPO lens allows users to zoom in on specific areas of an object to be viewed and identify details not visible on lower magnifications.The function of the HPO lens on a microscope is therefore to provide maximum possible magnification in order to view and identify details which can not be discerned while viewing the object through an objective lens with a lower magnification factor.
