Precisely what do you imagine as soon as anyone mentions the word magnification? A lot of folks think of the magnifying glass. These are available in several forms and sizes. To put it simply, a magnification glass is a convex lens that is employed to yield a magnified image of an item. The lens is commonly attached on a plastic body with a handle. You know, the one Sherlock Holmes carries! Indeed, that one Mr.Watson. These lenses are used for a large number of reasons, like vision aids, in microscopes, in telescopes, as burning glasses and so forth.

Of course, magnification lenses did not appear from out of no where. Like countless discoveries, magnification devices were seemingly uncovered by chance.

Proof has revealed that Romans’ had discovered and possibly even built elementary adaptations of a magnification device as far back as a hundred AD. Tools were crafted by using a glass globe and standard water to produce magnification which could then be used to examine books and other objects. The only identified implementations of this kind of tool was executed by first century Roman philosophers Seneca and Pliny the Elder. In fact these Roman philosophers had written about magnify glasses and burning glasses during that time. These glasses were likely naturally shaped crystals that exhibited these special features. Regrettably there is no evidence to show that actual magnifying lenses were developed at that time. It wasn’t till many centuries later that magnifiers would be widely used.

Another reference of a magnifying glass or a burning glass in published historical past occurs in the 5th century in a play developed by Aristophanes named The Clouds. This indicates that these types of devices were more wide spread than previously presumed for that time, however this still doesn’t indicate that a true comprehension of magnifying instruments and magnification as a whole was entirely realized.

Absolute understanding of optical lenses and magnification was likely not understood until the eleventh century. Details on the topic were rarely written about before this. Yet, in 1021 AD the Book of Optics had been published by the renowned scientist, Ibn al-Haytham. This publication practically rewrote how we have come to know optics today.

In the 12th century the Book of Optics had been translated into Latin and was subsequently referenced by Roger Bacon who identified the attributes of magnifying glasses in Great Britain in the Thirteenth century. This had been immediately superseded by the engineering of spectacles in Italy. This signaled the first prominent development and utilization of magnifying lenses in ‘modern’ time.

These days, magnification lenses appear in countless shapes and dimensions and are employed for a wide range of purposes. In recent times the level of quality of these lenses has improved, breeding the development of several innovative products such as cameras, projectors, high powered microscopes and telescopes. Vision aid items have likewise improved, not merely with the quality of eye-glasses but also with the launch of completely new items like contact lenses and the lighted magnifier.

The hand-held lighted magnifier isn’t all that unique from a standard magnifying glass, with one significant exception. A lighted magnifier includes a illumination source to make it simpler to differentiate the characteristics of the subject being magnified. Earlier versions were large and cumbersome to carry because of the big batteries and light bulb. Imagine a flashlight with a built-in magnifying glass. Not that useful when an individual wishes to transport a compact magnifier with them. However, this has improved recently given that LED lights tend to be a fraction of the size and can be powered by substantially smaller sized batteries. The end result is a smaller form factor, utlra vibrant, hand-held illuminated magnifier.
