Lab No. 2: The Microscope Light microscopy The bright field microscope is best known to students and is most likely to be found in a classroom. Visible light is focused through a specimen by a condenser lens‚ then is passed through two more lenses placed at both ends of a light-tight tube. The latter two lenses each magnify the image. Limitations to what can be seen in bright field microscopy are not so much related to magnification as they are to resolution‚ illumination‚ and contrast

PRACTICAL 3 QUESTIONS PART 1 Q 1. What is the diameter of the field of view of your microscope using the x10 objective (i.e. at a magnification of x100)? The diameter of the field of view using the x10 objective is 1800 µm. Q 2. What is the diameter of the field of view of your microscope using the x40 objective (i.e. at a magnification of x400)? The diameter of the field of view using the x40 objective is 400 µm. Q 3. What is the ratio of magnification between the x10 and x40 objectives?

Aherne-Williams Fibre-Optic Telecommunications Systems: Fibre-optic telecommunications is simply a method of transmitting information from one place to another extremely fast. This is done by shooting pulses of light through an optical fibre. Creating the optical signal involving the use of a transmitter‚ relaying the signal along the fiber‚ ensuring that the signal does not become too distorted or weak‚ receiving the optical signal‚ and converting it into an electrical signal. An optic-fibre is a small

Fiber Optic Safe Working Procedures Most of the standards‚ created by industry groups to insure product compatibility‚ they are not “codes” or actual laws that must be followed to be in compliance with local ordinances. The only mandatory standard is the NEC. The NEC specifies fire prevention standards for fiber optic cables. They are however‚ the standards we must follow. Installation Hazards: When installing burial or aerial cable‚ cables containing conductive materials could pose a potential

Determine the concentration of a solute in a solution by comparing the solution’s refractive index to a standard curve. To know about refractive index measurement first of all we know something about refractive index. What is refractive index? In optics the refractive index or index of refraction n of a substance (optical medium) is a dimensionless number that describes how light‚ or any other radiation‚ propagates through that medium. It is defined as ‚ Where‚ where c is the speed of light in vacuum

Fiber Optic Safety Rules 1) Keep all food and beverages out of the work area. If fiber particles are ingested they can cause internal hemorrhaging 2) Do not smoke while working with fiber optic systems. 3) Always wear safety glasses with side shields. Treat fiber optic splinters the same as you would glass splinters. 4) Never look directly into the end of fiber cables until you are positive that there is no light source at the other end. Use a fiber optic power meter to make certain the

an odd mixture of the two images. Normally‚ this does not happen because your visual system has developed many different ways to resolve ambiguity. Visual perception is essentially an ambiguity-solving process. This process is called "inverse optics." The visual system is also highly adaptive. It should be understood that both evolution and learning contribute to visual
