2.2. Visual observations Preliminary observations on the samples were per- formed using an Olympus SZ-40 stereomicroscope (10 and 20 objectives) equipped with an Olympus DP10 digital camera. Optical observations of the cross-sections were carried out using an Olympus BX60 in re ec- tion mode (with optical magni cations 50 to 500) equipped with a JVC KY-F1030 digital camera. The op- tical images were collected with re ected

light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000x. The electron microscope uses electrostatic and electromagnetic lenses to control the electron beam and focus it to form an image. These electron optical lenses are analogous to the glass lenses of a light optical microscope. Electron microscopes are used to investigate the ultrastructure of a wide range of biological and Electron microscope details of hair;

our present time. We also generally associate telescopes to astronomy like the Hubble Space Telescope. There is a rich history behind its invention and its further progression which we will now discuss. The first type of telescope invented was an optical telescope. This telescope has three designs‚ namely‚ refracting telescopes‚ reflecting telescopes and catadioptric telescopes (refracting and reflecting combined). Further progress was made in developing other kinds of telescopes such as the invention

The Compound Light Microscope Commonly binocular (two eyepieces)‚ the compound light microscope‚ combines the power of lenses and light to enlarge the subject being viewed. Typically‚ the eyepiece itself allows for 10X or 15X magnification and when combined with the three or four objective lenses‚ which can be rotated into the field of view‚ produce higher magnification to a maximum of around 1000X generally. The compound light microscope is popular among botanists for studying plant cells‚ in

device using three-times magnification. He uses a concave eyepiece coordinate with a convex objective lens. Lots of stories say that he got the idea from another eyeglass maker‚ Zacharias Jensen. They both lived near by and both worked on making optical instrument. However Lippershey are known as the creator of the telescope‚ therefore Jensen are know within inventing a compound microscope. Couple weeks later‚ Jacob Metius‚ a Dutchman‚ practiced for a patent for a telescope. Yet the government of Netherlands

vision device (NVD) is an optical installment that allows images to be produced in levels of light approaching total darkness. They are most often used by the military and law enforcement agencies‚ but are available to civilian users. The term usually refers to a complete unit‚ including an image intensifier tube‚ a protective and generally water-resistant housing‚ and some type of mounting system. Many NVDs also include sacrificial lenses‚ IR illuminators‚ and telescopic lenses. NVDs are mounted appropriately

OVERVIEW Nikon and Canon is as good as each other overall. Each makes equally excellent lenses at the same price points‚ and each makes DSLRs with the same technical quality in each format. The differences lie in ergonomics and how well each camera handles‚ which is what allows you to get your photo. Each are multi-billion dollar optical companies who have been making some of the world’s best optics for numerous consumer‚ industrial and military applications for decades and decades and decades
