Micolens are small lenses with a diameter smaller than 1 mm, they can work by diffraction, refraction or a combination of these two. When arranged regularly on a single substrate they form a microlens array. In order to be considered a good quality lens, microlenses must have qualities such as to low wavefront aberrations, consistency of focal length and pitch across the array, durability and low price. (Daly 2001) Microlens arrays have several applications, such as CCD arrays, digital…

The cornea, or lens, is a transparent covering of material at the front of the eye, which creates an image of an object by mixing light in a process known as refraction (Klein). During refraction the light rays pass through the cornea and pupil and hit the lens that creates an image on the retina. The retina then sends the image to the optic nerve that makes you able to see. The eye can work like this because it has its own lens that is able to focus on an image that is…

has come, scientists have created a type of bionic lens that allow humans to zero in on the tiniest of objects without the assistance of a third item such as the microscope. For hundreds of years, scientists have been using the microscopes to make major discoveries such as proving the existence of minuscule living organisms that cannot be seen to the naked eye. However due to the physical laws restricting light to pass through conventional lens to see these small items, we had begun to be…

Traditional lens are the typical, rounded design of contact lenses, which can correct near-sightedness (myopia) or farsightedness (hyperopia). Google contact lens are smooth spherical cell, they constructed a new LCD-based contact lens display, which also corrects myopia and hyperopia. In term of spherical, both of these lenses provide somewhat same type of treatment and corrections. Improves health As technology moves further into health treatment, and advanced digital diagnosis Google lens…

The American, representing males in the situation, is seen as holding all power and control, which reinforces a patriarchal system.

The beast, portrayed as a half-man half-wolf, highlights aggression and primitive instincts in humanity. Though rarely provoked, nearly every modern account of werewolf sightings involve the beast attempting to attack witnesses. Whether these sightings are fact or fiction, society has a fascination…

touch. Slime is usually sold in a variety of colors including: red, blue, green, pink and yellow. In fact, if you make your own slime at home you may add any color you would like. The properties of the slime are interesting and cool. Slime becomes thin and flows easier if it gets pulled slowly. Whereas, if you pull it fast, it will become thick and will rip apart. The reason why the slime will rip apart is because, as you pull the slime fast the chemical bonds break in the slime. Slime is so…
