High brightness sunlight readable monitors are typically used commercially in kiosks, vending systems, pipeline inspection systems, outdoor digital signage and advertising, in sports stadiums, in military vehicles, on ships for navigation systems, on bus and train platforms, and much more.
The nit (symbol: nt) is a non-SI name also used for this unit (1 nt = 1 cd/m 2). [1] The term nit is believed to come from the Latin word nitēre, "to shine". [2] As a measure of light emitted per unit area, this unit is frequently used to specify the brightness of a display device. The sRGB spec for monitors targets 80 cd/m 2. [3]
A tea light-type candle, imaged with a luminance camera; false colors indicate luminance levels per the bar on the right (cd/m 2). Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. [1]
A dead nit attached to a hair. No nit policy is a public health policy implemented by some education authorities to prevent the transmission of head lice infestation.The "no nit" policy requires the sending home and barring of all children who have nits (egg shells) on their hair from controlled settings such as school, summer camp or day care facilities.
This is a list of stars arranged by their apparent magnitude – their brightness as observed from Earth. It includes all stars brighter than magnitude +2.50 in visible light, measured using a V-band filter in the UBV photometric system.
The distance to the supernova remnant has been estimated to between 2 and 5 kpc (approx. 6,500 and 16,300 light-years), with recent studies suggesting a narrower range of 2.5 and 3 kpc (approximately 8,000 and 9,800 light-years). [10] Tycho's SNR has a roughly spherical morphology and spreads over an angular diameter of about 8 arcminutes.
The Dodge Nitro is a compact SUV [3] [4] manufactured and marketed by Dodge for model years 2007–2012 across a single generation — as a close variant of the second-generation Jeep Liberty. Both vehicles use a composite unitized construction integrating the body structure with full-length frame rails.
(The S 10 unit is defined as the surface brightness of a star whose V-magnitude is 10 and whose light is smeared over one square degree, or 27.78 mag arcsec −2.) The total sky brightness in zenith is therefore ~220 S 10 or 21.9 mag/arcsec² in the V-band. Note that the contributions from Airglow and Zodiacal light vary with the time of year ...
