Photographic lens

through the lens is in focus while everything outside of the lens frame is out of focus. The human eye is a fascinating organ. There are many parts of the eye that aid in allowing a person to see, but this paper will talk only the components that allow images to form on the retina. In general, the ciliary muscle can relax or contract to adjust the focal length of the lens. When the muscle is contracted, the curvature of the lens increases, thereby decreasing the focal length of the lens. When…

What’s the most common word that comes to mind in a week? Mine is sorry. Most common phrase? Always beginning in under, less than or lacking. You are underrepresented in society. You are lacking in the opportunities many other people have had. You’re less than prepared. Sorry for letting you down. But those are just words. Seeing is believing. Who do you see as you look in the mirror? Someone's loved one, someone’s support, or simply someone? Yeah, it takes one to know one and all that jazz, but…

An inverted fluorescence microscope is an inverted compound light microscope equipped with modules to internally separate the different wavelengths of light, and direct them to respective detection channels. Its main components include a light source, an objective, a filter cube and a detection unit, which can be an eyepiece or a camera (Fig.1). Filter cube is a component which separates a fluorescence microscope from a light microscope. It consists of one excitation filter, one emission filter…

The Kinect V2 is composed of a time-of-flight continues-wave camera with a resolution of 512*424 pixels (width*height), an RGB camera with a resolution of 1920*1080 pixels (width*height), an array of 4 microphones and some electronics for signal elaboration. The camera is able to acquire images at a maximum frequency of 30 Hz. Sending out invisible structures pulses into the scene whilst measuring the individual traveling time of each point in the pulse (See figure 3.1, page 16). The operating…

drawing of what you saw through both the high and low powered lens. Introduction- This lab is based on the compound light microscope. “A compound light microscope is a microscope that allows light to pass through a specimen and uses two lenses to form a image”. The compound light microscope has two main lenses. The two main lenses are the low powered lens and the high powered lens. The low powered lens is 10x, while the high powered lens is 40x. In this lab you will learn how to hold…

Journal Entry 1 I personally have myopia. I am negative 3.75 on each eye and wear eye contacts everyday. There are many things that are annoying about being myopic: wearing contacts, not being able to see without them, feeling blind without them, making sure you always have an extra pair of contacts on you in case you lose one. One of the more frustrating aspects of being myopic is whenever you are not wearing your contacts or glasses and you run into someone you know – and you have no idea who…

not seem to change when we move the lens closer and farther away from the box. Then, we find that the light rays converge after passing through the bi-convex and plano-convex lens and diverge after passing through the bi-concave lens. Therefore, the focal length of the bi-concave lens is negative. We also observe that the focal length of the plano-convex lens is greater than that of the bi-convex lens, which is due to the fact that one side of the plano-convex lens is flat while the other side…

objects that cannot be seen with the naked eye. We found that microscopes have many different parts to them, including the diaphragm, ocular lens, and objective lenses. There are three powers of magnification, scanning power (4x), low power (10x), and high power (40x). To find the total magnification, we multiplied the ocular lens (10x) by the power of the objective lens. The diaphragm lets a certain amount of light through to the specimen. The bigger the diaphragm hole the more light, and the…

for this purpose is the compound light microscope, it is called compound because it uses two sets of lenses the objective and the ocular. The ocular lens usually magnifies 10x. The objective lens can magnify 4x, 10x, 40x, or 100x. Hypothesis: To examine the slide of the three colored threads, and…

1. How are the photographs taken with a 3D microscope different than those taken with a regular camera? How are they similar? The 3D microscope photographs are used to show detail that a regular photograph could not, for example at a crime scene. The similarity is the basic image, it is the same image but the only difference it has with a 3D microscope is the detail shown. 2. How can photography allow us to view the world around us in different ways? Photography captures not a second of the…
