Lesson 2

This is the technique used to view objects that cannot be seen by the naked eye and is inevitable in the study of microbiology.

(a)  

The three main techniques used in the study of tiny organisms are Optical microscopy, Scanning probe microscopy, and this technique.

(a)  

Also known as the light optical microscope, this technique uses visible light and a system of lenses to magnify small images up to 2,000 times.

(a)  

These microscopes enable researchers to visualize submicron structures, determine their surface profiles, and observe selected cross-sections of transparent materials without slicing the samples.

(a)  

Images from an optical microscope can be captured by normal light sensitive cameras to generate this.

(a)  

Digital microscopes use these types of cameras, which allow the capture of a digital image directly on a computer screen without the need for eye pieces.

(a)  

This family of tools is used to make images of nanoscale surfaces and structures, including atoms, by 'feeling' the surface rather than viewing it directly with light.

(a)  

This lens condenses the light from the base illumination and focuses it onto the stage; it sits below the stage and typically connects the stage to the arm or frame.

(a)  

These knobs adjust the focus of the microscope and increase or decrease the level of detail seen when looking at the slide or specimen through the eyepiece.

(a)  

The circular opening in the stage where the illumination from the base of the compound microscope reaches the platform of the stage.
