How to Use a Compound Microscope in 12 steps

How to Use a Compound Microscope in 12 steps

Although there are many different types of compound microscopes, the steps for using them are pretty much the same.

1. If you haven’t used a microscope so far, you have to get to know the microscope and its parts, so you can follow next steps. Also, you have to take great care of your microscope, since it is a sensitive “gadget”.

2. Once you have you microscope, you’ll have to place it on a flat surface. There has to be enough free space, so that you have where to put and prepare your material. [Read more…] about How to Use a Compound Microscope in 12 steps

What has Numerical Aperture to do with the Microscope resolution?

What has Numerical Aperture to do with the Microscope resolution?

In microscopy, the numerical aperture of an optical system such as an objective lens is defined by:

\mathrm{NA} = n \sin \theta\;

where n is the index of refraction of the medium:

  • n = 1.00 for air
  • n = 1.33 for pure water
  • n = 1.52 for immersion oil

and θ is the half-angle of the maximum cone of light that can enter or exit the lens.

Who developed the compound microscope

Who developed the compound microscope

In order to get to the answer of this question, we have to make it clear what a Compound Microscope is. It is a magnifying object that features at least two lenses placed in a tube: an eyepiece and an objective lens, used to see objects that are too small for the naked eye, using the light.

You’ll say: you’ve described all the microscopes.

Well, yes. Generally, all today’s light microscopes, except for the 3D (stereo) microscopes, are Compound microscopes. So, what we are going to answer is who developed today’s light microscopes.

But first, a little bit of pre-compound microscope history. [Read more…] about Who developed the compound microscope

Difference between simple and compound microscope

Difference between simple and compound microscope

Optical microscope, or light, is the most common type of microscope. It can be SIMPLE, meaning that it’s consisted of a single lens, and it can be COMPOUND, consisting of several optical components in line. The most important differentiating factors are the number of lenses on each of these two microscopes and the level of magnification.

Microscope Types: The Complete List

There are many Microscope Types and we can classify them based on several aspects. We can classify them upon: what interacts with the sample to generate the image whether they analyse the sample via a scanning point their cost their versatility their area of application and performance Most acceptable classification is based on how the image is […]
