The focal length of a lens refers to the distance between the focus (or one of the foci) to the center of the thin lens. It can also be calculated using the equation 1/do + 1/di = 1/f. How do you calculate focal length? The focal length of a mirror and a lens can be calcula...
Importantly, the object (light source) distances need to be greater than the focal length of the selected mirror in order to obtain real images that can be projected on to a screen or flat surface. Reflecting on fraction addition: Using the mirror formula to visualise unit fraction addition ...
This work introduces a universal function that provides the optimal focal length of a mirror, given only the mirror's position relative to the receiver and the latitude, for a NS-oriented collector with a flat horizontal effective target. In a solar plant with the focal lengths defined by ...

A variable focal length lens consists of many micromirrors with degrees of freedom rotation and/or degrees of freedom translation and actuating components. As operating methods for the lens, the actuating components control the positions of micromirrors electrostatically and/or electromagnetically. The op...
