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.

Adjusting Koehler Illumination

Koehler illumination ensures that the specimen receives a bright uniform light. Only those areas actually seen are illuminated.

Simple Polarization Microscopy

It is not necessary to purchase a dedicated polarizing microscope to observe specimens in polarized light. A pair of linear polarizing filters is enough.

Enhancing Contrast

This article briefly outlines some contrast enhancing techniques that are used in microscopy.

Observing leaf veins

This is a simple but somewhat time-consuming preparatory technique. It is possible to isolate the vascular bundles of certain leaves and prepare them for microscopic observation. The prepared leaf veins make an ideal specimen for stereo microscopy. The microscope allows the students to perform a quality-check of their preparation.
