Transmission light microscopes are used to look at thin sections – the specimen must transmit the light which includes tissues, cell walls, crystalline components, and thin films, etc. Differential interference contrast optics microscopy.There are several different techniques for transmitted light that are used for sample analysis: This type of microscopy is used to distinguish morphological characteristics and optical properties of samples. The condenser and condenser aperture combination controls the light in a way that gives illumination that allows for the right balance of resolution and contrast. A Transmitted light microscope uses light that passes through a condenser into an adjustable aperture then through the sample into a series of lenses to the eyepiece. Visible Light Absorption Atoms and molecules contain electrons. In this section of Lesson 2 we will discuss how and why light of certain frequencies can be selectively absorbed, reflected or transmitted. to permit (light, heat, etc. The manner in which visible light interacts with an object is dependent upon the frequency of the light and the nature of the atoms of the object. to convey or pass along (an impulse, force, motion, etc.). For this type of light microscopy samples are required to allow light through them. to cause (light, heat, sound, etc.) to pass through a medium. Transmitted light microscopy is a type of light microscopy where light is transmitted, or passed through, a sample.
