Difference between compound microscope and dissecting microscope

Main difference

The main difference between the compound microscope and the dissecting microscope is that the compound microscope is the microscope that is used to observe small objects with high magnification power, while the dissecting microscope is used to dissect the sample.

Compound microscope vs dissecting microscope

We use a different kind of tool in biology like microscopes. They are very useful for observing microorganisms and pathogens, etc. that cannot be seen with the naked eye. There are different types of this device depending on their structure and function and they are used for a specific purpose. Two of those types are the compound microscope and the dissecting microscope. A compound microscope is a microscope that is used to observe the magnified images of small samples known as compound microscope, on the other hand, the dissecting microscope is the microscope that is used to examine and dissect the sample. Therefore, compound microscopes are made to look through a sample, whereas dissecting microscopes are designed to see the surface features of a sample and to dissect small insects, etc. Both types of microscopes are used to magnify an object by focusing light through lenses and prisms onto a sample. The light can act directly, or it can be reflected in nature, so that it can illuminate the object. Light is transmitted through the object in the case of a compound microscope on the other side; In a dissecting microscope, the object is seen with the help of reflected light. The light source is present below the sample in the case of a compound microscope, whereas; the light source is above the sample in case of dissecting microscope. A compound microscope has multiple objective lenses and an eyepiece, whereas a dissecting microscope has a single objective lens and two eyepiece lenses. A compound microscope has a high magnification power of up to 1000X; Besides,

Comparative chart
Compound microscope Dissecting microscope
A microscope that is used to look at magnified images of small samples is known as a compound microscope. A microscope that is used to examine and dissect the sample is known as a dissecting microscope.
Other names
It is also known as an optical microscope. Also known as a stereomicroscope.
Light source
A light source is present below the sample in the case of a compound microscope. The light source is present on the sample in the case of a dissecting microscope.
Object lighting
An object is observed through transmitted light in a compound microscope. In a dissecting microscope, the object is seen with the help of reflected light.
Power of increase
A compound microscope has a high magnification power of up to 1000X. A dissecting microscope has a low magnification power of up to 70x.
Resolving power
A compound microscope has high resolution power. A dissecting microscope has low resolution power.
Working distance
It has a shorter working distance of 4mm. It has a longer working distance of 150mm.
Sample preparation
The sample is specially prepared by staining, etc. to observe under a compound microscope. No preparation is required to view an object under a dissecting microscope.
Number of lenses
A compound microscope has multiple objective lenses and an eyepiece. A dissecting microscope has a single objective lens and two eyepiece lenses.
Function
The compound microscope is used to look at tiny and smaller things, like protozoa, bacteria and cells, etc. It is used to study the surface of the specimen, in microsurgery, for the study of dissections, in the manufacture of watches and small circuits, etc.
What is a compound microscope ?

A compound microscope is one that uses several objective lenses with different powers of magnification to view the samples. Use the light to observe the specimen. Therefore, the sample must be thin enough for light to pass through. Staining is also required to view different sections of a sample under a compound microscope. It has a magnification power of 400X to about 1000X and shows detailed characteristics of the samples. It has a shorter working distance of 4mm.

What is the dissecting microscope ?

A dissecting microscope is also known as a stereomicroscope. It has a magnification power of less than 70x. A ray of light is projected onto the sample. This type of microscope is used to view larger samples and to dissect small objects such as insects, etc. It has a working distance greater than 150 mm.

Key differences

  1. A microscope that is used to view magnified images of small samples is known as a compound microscope, while a type of microscope that is used to examine and dissect the sample is known as a dissecting microscope.
  2. A compound microscope is also called a light microscope, while the dissecting microscope is also known as a stereomicroscope.
  3. An object is viewed through transmitted light in a compound microscope; on the other hand, in a dissecting microscope, the object is seen with the help of reflected light.
  4. The light source is present below the sample in the case of a compound microscope. In contrast, the light source is present on the sample in the case of a dissecting microscope.
  5. A compound microscope has multiple objective lenses and an eyepiece on the other side, a dissecting microscope has a single objective lens and two eyepiece lenses.
  6. The sample is specially prepared by staining, etc. to observe under a compound microscope, whereas no preparation is required to observe an object under a dissecting microscope.
  7. A compound microscope has a high magnification power of up to 1000X; on the other hand, a dissecting microscope has a low magnification power of up to 70x.
  8. A compound microscope has a shorter working distance of 4mm, while the dissecting microscope has a longer working distance of 150mm.
  9. A compound microscope has a high resolution power, while a dissecting microscope has a low resolution power.
  10. The compound microscope is used to look at tiny and smaller things, like protozoa, bacteria and cells, etc. On the other hand, a dissecting microscope is used to study the surface of a sample, in microsurgery, to study dissections, in observation and fabrication of small circuit boards, etc.
Final Thought

The above discussion summarizes that the compound microscope is used to observe small objects with high resolution and magnifying power, while the dissecting microscope is a microscope with low magnification and resolution and is used to dissect small objects.
