Each objective lens has a different magnification. Multiply the magnification of the eyepiece by the magnification of the objective lens to produce total magnification. For example, a 10X ocular lens and a 40X objective lens will produce a total magnification of 400X (10 x 40 = 400).
What is the value of the smallest objective?If it is 4x,The total magnification = eye piece x objective lens= (10x) x (4x)= 40x
The objective lens is typically more powerful than the eyepiece lens in a microscope. The objective lens is responsible for magnifying the specimen, while the eyepiece lens further magnifies the image created by the objective lens.
The objective lens on a microscope is the lens closest to the specimen being observed. It magnifies the specimen and gathers light to form an enlarged image for viewing. Different objective lenses have varying magnification levels.
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.
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.
The lens closest to the eye in a microscope is called the eyepiece or ocular lens. It is where the viewer looks through to observe the magnified image of the specimen being examined.
The magnifying lens in an optical microscope is located in the eyepiece. This lens helps enlarge the image produced by the objective lens, allowing the viewer to see details not visible to the naked eye.
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.
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.
the magnifyings system include the eye piece i.e. ocular lens and objective i.e. parfocal lenses
