How to prevent Air Bubbles in Wet Mounts

There are several methods how bubbles can be reduced when making slides.


How to obtain the best resolution with your microscope

The resolution that a microscope is capable of achieving is probably the single most important factor that determines the quality of a microscopic image. Without a sufficiently high resolution, magnification is not possible without loss of quality. There are a variety of different factors that determine the achievable resolution. Some of these factors can not be actively influenced by the microscopist, others can. Some of the factors play a larger role, others a smaller one. In the following post, I want to summarize some of these factors.


Cover glass thickness and resolution

The thickness of the cover glass can have a significant impact on the resolution.


5 Rules of buying a microscope

I’ve been repeatedly asked for advice concerning the purchase of microscopes of hobby and amateur purposes. The following rules should help you in your choice.


Observing bacteria under the light microscope

It is possible to use non-toxic stains (such as ink for fountain pens) to stain yogurt bacteria in-vivo.


Required camera resolution for photography through the microscope

How many megapixels do you need? In this post I try to determine the required resolution.


Working with the condenser aperture diaphragm

The condenser aperture diaphragm (or iris diaphragm) is used to control the contrast and resolution of an image. This article explains the usage of the diaphragm.


The Condenser Aperture Diaphragm

In this post, the function of the condenser aperture diaphragm is explained. The purpose of the condenser is to concentrate the light onto the specimen, its diaphragm regulates resolution, contrast and depth of field.
