What are the magnifier?
A magnifying glass is a convex lens that is used to produce a magnified image of an object. The lens is usually mounted in a frame with a handle. A magnifying glass can be used to focus light, such as to concentrate the sun’s radiation to create a hot spot at the focus for fire starting.
How does a magnifier work?
A magnifying glass is usually a convex lens (a lens that bulges outwards), made of either glass or plastic. Light hits the glass at an angle, and it gets refracted towards the centre of the lens. Leaving the glass makes it refract even further, meaning, at some point, these rays of light converge together.

How are magnifying lens made?
The disc shape you have cut out curves outwards, so is a convex shape. By adding the water the light that passes through is refracted meaning that it is bent inwards, creating a lens effect and enlarging the size of the letters. So you have then created your very own magnifying glass!

What is the HPO in microscope?
The high-powered objective lens (also called “high dry” lens) is ideal for observing fine details within a specimen sample. The total magnification of a high-power objective lens combined with a 10x eyepiece is equal to 400x magnification, giving you a very detailed picture of the specimen in your slide.

What is a dome magnifier?

They are plano-convex lenses: the flat (planar) surface is placed on the object to be magnified, and the convex (dome) surface provides the enlargement. They usually provide between 1.8× and 6× magnification.
How does a video magnifier work?
Video magnifiers are electronic devices that use a camera and a display screen to perform digital magnification of printed materials. The display screen is usually LCD or a similar flat-screen technology (although older video magnifiers have used CRT displays), and the device usually includes a lamp to illuminate the source material.
