BASIC TERMS
Focal Length: Focal length is the distance from the center of the lens (or lens system) to the viewed object when in focus.
Working distance: Working distance is measured from the lowest protruding portion of the magnifier below the lens, usually the
bottom of the shade or shade housing, to the object when it appears in focus.
Diopter (D): A term used to identify the refractive (light bending) capacity of a lens. It also relates magnification to focal length.
Each diopter increases magnification by 25%, e.g. 4 diopter equals a 100% increase above original size.
Field of View (FOV): Field of view is the area which is visible as seen through a lens. Wide-view rectangular lenses allow a greater
viewing area than round lenses which force the user to rely solely on the center, undistorted section of the lens for optimal magnifica-
tion clarity.
Magnification: The degree to which the viewed object is enlarged. Magnification is usually expressed by a number followed by the
symbol ‘X’ as in 1X, 2.25X, etc. To determine the level of magnification based on diopters used, divide the total diopters by 4 and
add 1. E.g. 20D/4+1=5X.
Selecting the Right Luxo Magnifier
To select the Luxo Illuminated Magnifier that best suits your needs, follow these steps:
1. Determine the desired magnification for your needs. Remember, as you increase magnification, you decrease both the focal
2. Check the chart on the back page of this brochure to find the right diopter to achieve that magnification. (The vast majority
3. Note the focal length and lens diameter that correspond to the magnification and lens diopter you have chosen, and make sure
4. Select the primary and secondary lens combination required to achieve your desired magnification.
5. As a general rule, lenses or lens combinations above 5-diopter are recommended for inspection purposes only due to shorter
length and the viewing area.

working distances. A magnification requirement in excess of 4X normally requires a microscope.
BASICS OF MAGNIFICATION
Examples of Magnification
With no magnification
1.75X or 175% of its size as seen through a 3D lens.
3.50X or 350% of its size as seen through a 10D lens.
4.75X or 475% of its size as seen through a combination
of a 5D primary lens and a 10D secondary lens.
6.00X or 600% of its size as seen through a combination
of a 10D primary lens and a 10D secondary lens.
Using a Luxo Magnifier
1. Use both eyes. Luxo lenses are designed as ‘working tools’. They should be

enough to your eyes (about 8” to 10”) so that you have the maximum
magnification without distortion. Don’t lean back away from the lens to
increase magnification.
