A magnifier lamp is an important device for individuals performing very detailed work, and it is also extremely helpful for individuals with vision difficulties. Magnifier lamps allow the users to observe the minute details of an object that may otherwise be missed. All this while helping to reduce strain to the eyes and eye fatigue.
You must do some research when it comes to picking the correct magnifier lamp. Let’s talk specs.
Diopters and lens curvature
Diopter is a reference to the lens’ curve. The curvature of the lens becomes greater in relation to the increase in the diopter. The object is made to look bigger by the rays of light as they deflect to fill a bigger part of your retina due to the increasing curvature. If the diopter is higher, the magnification of the lens greater.
Power and diopters
How much greater in size an object is made to appear via a magnifier lamp lens is referred to as its power. The power is noted with a number followed by an X, for example 2X or 4X. Diopters, when divided by four, gives you the amount of power. To provide an example, an 8 diopter lens makes an object appear to double in size, compared to what you can see with the naked eye.
Focal length
The distance from where the rays of light converge putting the object you are looking at in perfect focus and the middle of the lens, is the focal length. This is also referred to as “working distance”. When working with magnifier lamps and tools, focal length becomes all the more important. When power increases, focal length decreases; so higher power lenses provide less room to work in.
Field of view
The size of the area under the lens that is magnified and in focus is known as the field of view. Increasing the power decreases the field of view. The problem is, while a more powerful lens magnifies the little details, it also lessens the overall amount of the object that is visible through it. You must choose between the level of magnification of the object, and the size of your field of view.
Proper lighting
A good amount of lighting is also needed in getting a good view of an object. This is why the quality of the light should be carefully considered before choosing a magnifier lamp. Though certain magnifier lamps are equipped with fluorescent lights, they can also be equipped with full spectrum bulbs if you want the rewards of natural light. Another thing to consider is the position of the light source in relation to the lens.
Look ma, no hands
Rather than holding a lamp or magnifier, it is much simpler to have your hands available to hold an object. With an adjustable arm magnifying lamp, your hands are free to do whatever needs to be done, whether it’s reading the evening paper, tying flies. or cross stitching. A hands-free magnifier lamp is a must-have if your work requires you to use both of your hands.
