Important terms • Magnification: ratio of an object’s image size to its real size • Resolving power: minimum distance between two points at which they are still distinguishable as different objects (measure of clarity) • Working Distance: distance between specimen and lens (higher magnification = smaller working distance) • Field of View: area visible through the ocular • Depth of field: amount of vertical distance that is in focus

Important terms
• Magnification: ratio of an object’s image size to its real size
• Resolving power: minimum distance between two points at which they are still distinguishable as different objects (measure of clarity)
• Working Distance: distance between specimen and lens (higher magnification = smaller working distance)
• Field of View: area visible through the ocular
• Depth of field: amount of vertical distance that is in focus
Important relationship
• Total magnification = ocular magnification X objective magnification
• As magnification increases: Working distance decreases Field of View gets smaller Depth of view decreases
