WebAug 19, 2013 · Heat waves, dust, humidity, glare, wind and air currents during the day all reduce image quality and the greater the magnification, the more drastic the reduction in image quality. Simply put, there will be days when anything over 30x will appear as mush, but there will also be those clear, calm days when you can use 60x to good advantage. In optics, optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device: P = 1/f. High optical power corresponds to short focal length. The SI unit for optical power is the inverse metre (m ), which is co…
