Introduction of microscope: How to make a microscope?

What is a Simple Microscope? Define Microscope
Simple Microscope Definition: A Simple Microscope meaning is used to see a magnified image of an object. Antonie Van Leeuwenhoek, a Dutchman, invented the first simple microscope, consisting of a single powerful magnetic lens that rotates to detect tiny freshwater insects. It is composed mainly of light microscopes. The main property of the target lens used in microscopes is to produce a virtual, upright and magnified image when the object is placed within a fixed height. A convex lens used in a microscope is to create a simple microscope. Convelenses areis widely used s a reading glass or magnifying glass. Now, to obtain high magnification, a combination of two or more convex lenses is used to create an integrated microscope.

What Are the Parts of a Simple Microscope?

A Simple Microscope contains various optical components and other supporting (or mechanical) components as discussed in this section, the layout of a simple basic microscope with its various labeled numbers. The Eyepiece connected to the lens via a tube. The eyeball is the lens where the image of the object can be seen. Tube length varies by rotating the button so that a clear image is obtained by changing the focus. The objective lens enhances magnification.

Parts of a Simple Microscope

The sample platform, made of metal foil, consists of metal clips holding a sample, which is placed on a glass slide, under observation. The mirror focuses on the light of the sample. All components are grounded.

The base is a component of equipment that provides support for the capture of other of other parts of the microscope. The arm of the microscope is connected to a physical object.

Lens used in simple microscope magnification

Basically, increasing the size of the object and the size of the image. The lens magnification figure is given below:

Magnification (M) = Himage / Object

However, in the case of a simple microscope, a short-lived convex lens is used to magnify the image of an object, the angle is passed to the eye for object and image.

The distance between the object and the centre of the curved lens.

Using a lens formula given as :

1/F = 1 /(−U) −1/ (−D)

, the number 3 can be written as M = 1 + D/F

M = 1 + D/F

Here, M describes the magnification of a simple microscope, D is a small distance of contrast view and F is the focal length of the convex lens. Since ‘F’ is in the denominator in the equation of magnification, that is why a short length of focus can lead to higher magnification.

A Simple Microscope trial

Here, we perform a simple test to calculate the magnitude of an F-centered biconvex lens that acts as a magnifying glass.

Resources needed:

Biconvex lens with short length focusing on ‘F’ and handle.

Newspaper article with low font size.

Process:

Place the reading under the biconvex lens with your eyes next to the lens.

Slowly move the lens to the article and move your head through the lens to view it.

As the lens moves closer to the article, you will notice that the letters of the alphabet will become smaller and blurry in reading.

As you move towards the lens you will see a clear and enlarged image of the printed alphabet in the articles. Think of a position as an 'A'. In this position, let's say the distance between the lens and the article is 'D'.

If you pass this position, the image will be enlarged but blurred and difficult to read.

Using the formula, M = 1 + D/F

magnification can be calculated.

Conclusion:

A simple test can be performed to detect lens magnification. Magnification basically tells us how much an image of an object will be formed by a particular lens.

What Are the Parts of a Simple Microscope?

The following are the components of a Simple Microscope and their functions:

Eyeball: A lens used to study samples and placed on top. It has an increase of 10X to 15X.

Baseline: This provides microscope support.

Tube: This is used to connect an eyepiece to the target lens.

Target lenses: These are available in 10X, 40X and 100X magnification lenses and have color coding. The lower electric lenses are shorter lenses and the upper electric lenses are much longer.

A flexible nose piece: This is also known as a turret. It is used to capture other purpose lenses and can be changed while viewing samples.

Diaphragm: Used to control the amount of light passing through the stage.

Stage: It is a platform used to place slides with samples.

Stage Clip: This is used to hold slides in the right place.

Adjust location button: Used to focus on scanning.

Good repair box: Used to focus on oil.

Arm: Used to support the tube and connect to the base of the microscope.

Power switch: A primary power switch used to turn the microscope on or off.

Condenser: Used to focus the light on the sample and uses 400X electric lenses.

Use of a Simple Microscope

  • Used in pedology (study of soil particles)
  • It is used by a dermatologist to diagnose various skin diseases.
  • It is used in microbiology to study algae samples, fungi etc.
  • It is used by carpenters to obtain an enlarged view of fine jewelry.

Frequently Asked Questions (FAQs)

1. How many lenses are in a simple microscope?

 A Simple Microscope contains a single lens that is traditionally called a loupe. A well-known example today is the reading or magnifying glass. Modern high-resolution lenses are usually made of two-dimensional glass materials that produce a colour-coded image.

2. Which lens is used in a simple microscope?

A convex lens is used to create a simple microscope. A convex lens is widely used and widely used as a reading glass or magnifying glass.

3. What is an example of a simple microscope?

Examples of simple microscopes include reading glasses, decorative ornaments, and pocket magnifiers. ... There are two types of integrated microscopes that use light to detect visible (or flexible) objects and invisible objects. An opaque object requires reflective light from an object through the optic tube lens.

4. Which convex lens is used with a simple microscope?

Converting the lens is called a convex lens that converts the rays of the light of the event to the same as the main axis at the same time; this is why flexible lenses are used in objects such as microscopes to focus on minute particles.

5. Why is a convex lens used with a microscope?

In the microscope, we often use a convex lens because the convex lens even magnifies images. Microscopes produce highly enlarged images of very small objects for this purpose the convex app is very useful. ... However, between the three lenses, the lens located at the end of the microscope produces a transformed and enlarged image.
