What defines quality loupes?
• Resolution: The capability to visualize small structures, set apart by the quality of the optical design and the use of precision lenses. • Field Width: The size of the area being viewed through loupes. • Field Depth: Range of focus delivered by the loupe (an average of four to five inches). • Weight: The comfort of the complete frame and loupe system. • Magnifying Power: The size of the image. Since there is no standard measurement for magnifying power in the loupe business, it really is only a rough guide when purchasing a system. • Working Angle (angle of declination): Allows the user to work in a comfortable, ergonomically correct position.
