Telescopes Hans Lippershey (1570 - September 1619) was a Dutch lens maker. Lippershey is believed to be the first to apply for a patent for his design‚ a few weeks before Jacob Metius (a Dutch instrument maker and optician)‚ and making it available for general use in 1608. The telescope invented by Lippershey was composed of a convex and a concave lens‚ as this construction did not invert the image and had only a magnification of just 3x. Galileo’s telescope improved the original Dutch telescopes

Photometry Like all waves‚ light carries energy. The section of the optics‚ which are considered energetic characteristics of light in its broadcasting‚ distribution and interaction with a substance called Photometry. 1. Flow of light energy - energy transmitted through a surface per unit time. For example‚ the pupil of the eye glass window. If a body absorbs light fell on it‚ its internal energy increases‚ and thus its temperature increases. By changing temperatrata judge the flow of light

scientists have recently found that they‚ along with other ordered non-periodic structures‚ exhibit unique optical effects as well‚ specifically negative refraction. To understand how ordered non-periodic structures are tested in the field of optics‚ one must first understand photonic crystals: crystals which exhibit effects of photon-directing similar to the electron-directing effects of semi-conductor crystals. The resulting phenomena occur by the fact that photonic crystals have dielectric

still being littered with ribs of broken ships whose captains couldn’t see the shore line. In 1822 Augustin Fresnel‚ a French physicist and engineer invented a lens that would change light houses everywhere. Fresnel contributed to the theory of wave optics and studied the behavior of light both theoretically and experimentally. Fresnel worked on numerous formulas to calculate the way light changed directions‚ while passing through the prisms. He worked with some of the most advanced glass makers of

An electron microscope is a type of microscope that produces an electronically-magnified image of a specimen for detailed observation. The electron microscope (EM) uses a particle beam of electrons to illuminate the specimen and create a magnified image of it. The microscope has a greater resolving power than a light-powered optical microscope‚ because it uses electrons that have wavelengths about 100‚000 times shorter than visible light (photons)‚ and can achieve magnifications of up to 1‚000‚000x

microscopes can be used to view things such as biological tissues and organisms. Also‚ another popular microscope used in human biology is the stereo microscope‚ which is commonly used to dissect and examine human tissue. Discussion When studying the “optics” slide in the interactive section of this lab it displayed image orientation. To display this it took the letter “e” and showed you the standard view to the naked eye and then it showed you the view through a light microscope and it looked very different

The electron microscope‚ instrument that produced the first magnified image showing three-dimensional’ and highly magnified image of a small object. It directs a beam of electrons rather than light through a specimen. The beam of electrons is created from an electron gun. This beam then travels through the length of the microscope cylinder‚ which contains the lenses‚ the specimen chamber‚ and the image-recording system. Two types of electron lenses are used‚ electrostatic and electromagnetic
