A principal focus or focal point is a special focus: For a lens , or a spherical or parabolic mirror , it is a point onto which collimated light parallel to the axis is focused. Since light can pass through a lens in either direction, a lens has two focal points – one on each side.
The highest practices in Tibetan Buddhism point to the ability to bring the subtle pranas of an entity into alignment with the central channel, and to thus penetrate the realisation of the ultimate unity, namely, the "organic harmony" of one's individual consciousness of Wisdom with the co-attainment of All-embracing Love, thus synthesizing a ...

A system is focal if an object ray parallel to the axis is conjugate to an image ray that intersects the optical axis. The intersection of the image ray with the optical axis is the focal point F ′ in image space. Focal systems also have an axial object point F such that any ray through F is conjugate to an image ray parallel to the optical axis.
A separation of exactly 1 focal length is also inadvisable since it renders the dust on the field lens disturbingly in focus. The two curved surfaces face inwards. The focal plane is thus located outside of the eyepiece and is hence accessible as a location where a graticule, or micrometer crosshairs may be placed.
A point of contact (POC) or single point of contact (SPOC) is a person or a department serving as the coordinator or focal point of information concerning an activity or program. A POC is used in many cases where information is time-sensitive and accuracy is important.
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
Point of view shot (Often abbreviated as 'POV'). A shot which shows an image from the specific point of view of a character in the film. Racking focus A shot employing shallow focus in which the focal distance changes so that the background is gradually brought into focus while the foreground is gradually taken out of focus or visa versa ...
