Field of view is the area of the inspection captured on the camera’s imager. The size of the field of view and the size of the camera’s imager directly affect the image resolution (one determining factor in accuracy). Working distance is the distance between the back of the lens and the target object.
NFC's maximum working distance of less than 20 cm reduces the likelihood of unwanted interception, making it particularly suitable for crowded areas that complicate correlating a signal with its transmitting physical device (and by extension, its user).
In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled.
February 22, 2024 at 12:04 PM. For many Americans, commuting to work is part of their everyday life. The most recent data show the average American commuter spends around 25.6 minutes on the way...
The United States Marine Corps began allowing remote work in 2010. Remote work (also called telecommuting, telework, work from home —or WFH as an initialism, hybrid work, and other terms) is the practice of working from one's home or another space rather than from an office .
The distance from the objective lens to the surface (called the working distance) is typically comparable to that of a conventional optical microscope. It varies with the system optical design, but working distances from hundreds of micrometres to several millimeters are typical.
Increasing the magnification and the numerical aperture of the objective reduces the working distance, i.e. the distance between front lens and specimen. Numerical aperture versus f-number Numerical aperture of a thin lens. Numerical aperture is not typically used in photography.
Flange focal distance. For an interchangeable lens camera, the flange focal distance ( FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance ( FBD ), flange focal length ( FFL ), back focus [1] or register, depending on the usage and source) of a lens mount system is the distance from the mounting flange (the ...
For example, a lens that can focus at 1.5 m combined with a +3 diopter close-up lens will give a closest working distance of 1.5/ (3×1.5 + 1) = 0.273 m . The magnification reached in those conditions is given by following formula: MX being the magnification at distance X without the close-up lens.
Inverse-square law. S represents the light source, while r represents the measured points. The lines represent the flux emanating from the sources and fluxes. The total number of flux lines depends on the strength of the light source and is constant with increasing distance, where a greater density of flux lines (lines per unit area) means a ...
