Magnification Basics Understanding these optical principles is essential for selecting the right loupe and ensuring predictable performance.
Key Concepts
• Working Distance (WD) The distance between the user’s eyes and the treatment area. The loupe must be customized for the user’s natural working posture.
• Field of View (FOV) The size of the area visible through the loupes. Higher magnification = smaller field of view.
• Depth of Field (DOF) The range in which the object stays in focus when moving closer or farther. Higher magnification = shallower depth of field.
• Magnification vs. Comfort As magnification increases:
The image becomes larger
Light decreases
Head movement tolerance decreases
Precision increases
Comfort requires more training and stability
Choosing the right magnification means balancing clarity, comfort, and clinical purpose.
