What is the function of the medium power objective lens on a compound microscope?
What is the function of the medium power objective lens on a compound microscope?
Stage – used to support the slide Stage clips- used to hold the slide in place Diaphragm- Used to regulate the amount of light Light source- provides light Low power objective- has the lowest magnification and is the shortest objective Medium power objective – increases the magnification High power objective- provides …
What is the function of the low power objective lens?
Low power objectives cover a wide field of view and they are useful for examining large specimens or surveying many smaller specimens. This objective is useful for aligning the microscope. The power for the low objective is 10X. Place one of the prepared slides onto the stage of your microscope.
What is the function of high power objective?
High Power Objective (40x): This objective (sometimes called the “high-dry” objective) is useful for observing fine detail such as the striations in skeletal muscle, the arrangement of Haversian systems in compact bone, types of nerve cells in the retina, etc.
What is the function of the eyepiece and objective lens?
Every microscope has an eyepiece lens, which is the lens at the top that you look through. A tube connects the eyepiece lens to objective lenses, which enhance the magnification power of the eyepiece lens.
What is a medium power objective?
There are 3 objective lenses, and each has a different magnification power (10x, 40x, 100x)The medium power objective lens is 40x. This objective lens will achieve the greatest magnification and has a total magnification of 1000x (10x eyepiece lens x the 100x objective equals 1000).
What are the two functions of objective lens?
The objective itself is usually a cylinder containing one or more lenses that are typically made of glass; its function is to collect light from the sample. Microscope objectives are characterized by two parameters: magnification and numerical aperture. The magnification typically ranges from 4× to 100×.
