With 2.5x, 4x, or 5x magnification you will be able to observe intricate details of your work area more clearly and perform the most delicate of surgical work on the smallest possible scale. Freedom of movement and angle adjustment means that you will no longer need to bend forward to get closer to your work area in order to see better.
Magnification Choice
These surgical loupes are available in either 2.5x, 4x, or 5x magnification.
A 4x or 5x magnification surgical loupe reveals incredible detail but provides a small field of view (30mm wide) and your working distance has to be maintained more accurately because of narrower depth of field (area in focus). Choose a 4x or 5x loupe if you want to focus on a narrow work area and need to see the details that higher magnification affords.
The lower 2.5x magnification results in a wider field of view (50mm), allowing you to monitor a broader work area. Because of the greater depth of field, the 2.5x surgical loupes provide for more freedom of movement as they are less sensitive to changes in your working distance.
Selecting Your Working Distance
People below 5'-7" in height usually need a working distance of 340mm (250-375mm) and those taller usually need a working distance of 420mm (300-450mm).
