One diopter is the power of the lens with the second focal length |
|
Answer» '' The POWER in DIOPTERS ism the reciprocal of the focal length in meters(or meters,if you prefer). So a focal length of 1 m is 1 DIOPTER, while a focal length of 0.25 m is 4 diopters. If ''2.5 power'' REALLY means 2.5 diopters,then the LENS' focal length is 400 m. |
