... At close proximity the lens is also able to capture most of the emitted light, focusing this to a tight spot with high power density. Such an assembly is ideal for optical coupling to a fibre (see Figure 3(a)). To test its efficiency, the aperture of a 2mm-diameter plastic optical fibre was aligned ...

... Bacterial or animal cells are difficult to be seen using the light microscope unless the sample is dried and stained. This microscope enhances the slight difference in refractive index between the cells and the medium and thus can be used to visualize the living bacteria and platelets, in which the ...

10.2 Diffraction Notes
... • If we place a monochromatic light, such as a laser so that the light goes through a single slit, the light is diffracted. • The diffraction from the light will cause a pattern of constructive and destructive interference which will be seen as dark and light bands. ...

INTRODUCTION
... The choice of wavelength depends upon the loss profile of the medium. For optical fiber the wavelength has to be 1300nm or 1550nm for low loss. The spectral width has direct bearing on the data rate which the medium can support. Larger the spectral width, smaller is the data rate. A semiconductor la ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
