R1= Radius of curvature of the first surface of the lens R2= Radius of curvature of the second surface of the lens For a converging lens, power is taken as positive and for a diverging lens, power is taken as negative. Definition for the Power of Lens Unit The S.I. the unit of pow...
If the focal length is in meters (m), the lens power is determined in Diopters (D) since the unit of power of a lens is the Diopter. Also note that the optical power of a converging lens is always positive, while the optical power of a diverging lens is also always negative. Optics...

Modern lens designs are capable of resolving greater than 10 gigapixels, while advances in camera frame-rate and hyperspectral imaging have made data acquisition rates of Terapixel/second a real possibility. The main bottlenecks preventing such high data-rate systems are power consumption and data st...
