An autocollimator works by projecting an image onto a target mirror and measuring the deflection of the returned image against a scale, either visually or by means of an electronic detector. A visual autocollimator can measure angles as small as 1 arcsecond (4.85 microradians), while an electronic autocollimator can have up to 100 times more ...
The Mac OS Calculator as it shipped in 1984, with System 1 Apple's iOS calculator app adjacent to a Braun ET 66 electronic calculator. The Calculator program has a long associated history with the beginning of the Macintosh platform, where a simple four-function calculator program was a standard desk accessory from the earliest system versions.
The iPhone calculator is great for crunching numbers in a pinch, but you can also use it to have some fun with your friends and family. Here are some cool calculator tricks you can use to find ...
It is possible to calculate how closely the mirror surface resembles a perfect parabola by placing a Couder mask, [7] Everest pin stick (after A. W. Everest) [8] or other zone marker [9] over the mirror. A series of measurements with the tester, finding the radii of curvature of the zones along the optical axis of the mirror (Y-axis).
If mirror R is stationary, then the slit image will reform at S. However, if the mirror R is rotating, it will have moved slightly in the time it takes for the light to bounce from R to M and back, and the light will be deflected away from the original source by a small angle, forming an image to the side of the slit.

With LCD screens, some manufacturers have opted to measure the contrast ratio and report the viewing angle as the angle where the contrast ratio exceeds 5:1 or 10:1, giving minimally acceptable viewing conditions. The viewing angle is measured from one direction to the opposite, giving a maximum of 180° for a flat, one-sided screen.
The sagitta also has uses in physics where it is used, along with chord length, to calculate the radius of curvature of an accelerated particle. This is used especially in bubble chamber experiments where it is used to determine the momenta of decay particles. Likewise historically the sagitta is also utilised as a parameter in the calculation ...
