What is the function of an objective lens on a microscope?
Objective lens on a microscope collects the light emerging from the sample and focuses it into the objective turret. Its primary role is to increase the magnification used for viewing.usually, there are three or four objective lenses on a microscope,
Explain why an inverted image is seen under a compound microscope?
The microscope you are using is probably old, and it has an odd number of convex lenses between the object and your eye. in addition to enlarging (or reducing) an image, an optical convex lense also inverts the image. If you were to invert the inverted image again, using another lense, then the resulting image will appear upright. So a microscpope with three lenses (most likely the number of lenses in the microscope you are using) inverts the image three times, resulting in an upside-down image. A microscope with four lenses shows an upgright image. That is why modern microscope manufacturers use an even number of lenses in a microscope (and in binoculars).
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 parts do compound microscope?
The three basic structural components of a compound microscope are the head, base and arm. then the main parts are objective lens near object, eye piece near eye and the stage to place object. it has coarse and fine adjustments to focus the object
How is a stereo microscope different from a compound microscope?
Compound microscope - a microscope which uses multiple lenses to collect light from the sample, and then a separate set of lenses to focus the light into the eye or camera. It shines a light from beneath the stage, going up through the object being examined.Stereo microscope - a microscope designed for low magnification observation of an opaque object. It shines a light onto the object, rather than shining it up through the object. It uses two separate optical paths with two objectives and two eyepieces to provide slightly different viewing angles to the left and right eyes. This produces a three-dimensional visualization of the object.
Attached to the revolving nosepiece of a microscope are three or four small lenses called?
They are called objective lenses.
What mechanical part of the microscope holds the three objectives?
Objective lenses you can see 3 - 4 objective lenses attached to the end of the tube.
What is the objective on a microscope?
the objective is the lens, there is the main ocular lens which you look through and then this leads to the turret. on the turret are 3 (usually) objective lenses which are usually 4x, 10x and 40x. so the objective are three lenses which change the amount of magnification on the microscope. :)

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.
Does a compound microscope have one lens?
Most microscopes have 4 to 5 lenses. The lenses are:The three Objects (which are the three things that you use to microscope)The lens that you you put your on.And the mirror lens.

The objective lens on microscope?
Used in conjunction with the eyepiece lens, the objective lens is what gives an optical microscope its ability to produce magnified images. There are normally three to four objective lenses on microscopes, ranging from 4X to 100X magnification, where the stronger lenses are larger. When coupled with the eyepiece lens, the magnification of a microscope ranges from 40X-1000X, though special conditions are required to achieve a sharp image at 1000X magnification.
What is the objective lens?
In an optical instrument, the objective is the optical element that gathers light from the object being observed and focuses the light rays to produce a real image. Objectives can be single lenses or mirrors, or combinations of several optical elements. They are used in microscopes, telescopes, cameras, slide projectors, CD players and many other optical instruments. Objectives are also called object lenses, object glasses, or objective glasses.
How many lenses does a simple microscope have?
Robert Hookes microscope had either two or more lenses. a simple microscope has one lens in it.
