Hand magnifiers facilitate many of the tasks we perform at work and in our private lives that require detailed, precise vision. With the VisuLook classic, by utilizing the highest possible magnification, image quality and distortion have been optimized so that no aberrations of any consequence occur.
The hand magnifiers are labeled with their refracting power (D), which can be used to calculate the magnification on the basis of conditions of use. Each magnifier has a hard protective coating and comes with a matching case.
Refracting (D) power: 20D
Magnification for reference distance of 0.25m (D/4): 5x
Optically effective diameter: 55mm
