The points on the optical axis OO' (see Figure 1) of a centered optical system that can be used to construct the image of an arbitrary point in space for objects in the paraxial region, which is the region around the axis of symmetry of the system where a point is represented by a point, a straight line by a straight line, and a plane by a plane.

How do optical isomers rotate plane of plane polarised light?
REFER : optical rotatory dispersion
True or false The number lines that form a Cartesian coordinate system are called the axes and the point where they intersect is called the center?
This is False the correct definition is this: The number lines that form a Cartesian coordinate system are called the axes and the point where they intersect is called the origin.
Why is a small critical angle desirable for optical fibers What problems could be caused if the critical we're increased?
because a smaller critical angle means that it is easier for total internal reflection to occur, which is the desirable quality in an optical fibre.
How homogenous co-ordinate system differ from cartesian system?
We assume that the ambient space is equipped with the standard Cartesian coordinate system and specify points by their Cartesian coordinates.The Cartesian coordinates of a point in the plane are a pair (x,y).The homogeneous coordinates of a point in the plane are a triple (x,y,w) with w!=0. The Cartesian coordinates of a point with homogeneous coordinates (x,y,w) are (x/w,y/w).Remark: We notice that the homogeneous coordinates of a point are not unique. Two triples that are multiples of each other specify the same point.The Cartesian coordinates of a point are of type double in the floating point kernel and of type rational in the rational kernel. The homogeneous coordinates of a point in the rational kernel are of type integer. Points in the floating point kernel are stored by their Cartesian coordinates.For points in the rational kernel it is more efficient to store them by their homogeneous coordinates, i.e., to use the same denominator for x- and y-coordinate.For compatibility also points in the floating point kernel have homogeneous coordinates (x,y,1.0). These homogeneous coordinates are of type double.
What is the nyquist theorem?
in automatic control the nyquist theorem is used to determine if a system is stable or not. there is also something called the simplified nyguist theorem that says if the curve cuts the "x-axies" to the right of point (-1,0) then the system is stable, otherwise its not.
How cardinal point of optical system located?
he points on the optical axis of a centered optical system that can be used to construct the image of an arbitrary point in space for objects in the paraxial region, which is the region around the axis of symmetry of the system where a point is represented by a point, a straight line by a straight line, and a plane by a plane.
What has a focal point?
A lens, mirror, or any optical system that can converge or diverge light rays to a specific point has a focal point. This point is where the light rays meet or appear to diverge from after passing through the optical system. The location of the focal point depends on the shape and properties of the optical system.
Conjugated principal point?
The conjugated principal point is a term used in optics to refer to the point where the chief ray of a light ray bundle passes through the optical axis after being reflected or refracted by an optical system. It is also known as the focal point or image point. The position of the conjugated principal point depends on the characteristics and parameters of the optical system.
What are the optical system of a compound microscope?
the optical system of a microscope is the objectives
Is the vanishing point just an optical illusion?
yap.. its just an optical illusion
Which cardinal point begins with E?
east
What term indicately the point where reflected light rays meet along optical axis?
A focal point is the point where reflected light rays meet along an optical axis.
What does optical system mean?
"Optical" means related to light, often to visible light. So, a system that works with light.
What is optical center of lens?
The optical center of a lens is a point on the lens axis where light passing through the lens does not deviate, regardless of the angle of incidence. It is often used as a reference point for optical calculations and design. The optical center is typically at the geometric center of a lens with a symmetrical shape.
What is EOS in Canon digital camera?
EOS is Electro-Optical System. It controls the optics of a lens through electronic system.
What term indicates the point where reflected light rays meet asking an optical axis?
The term that indicates the point where reflected light rays meet along an optical axis is the focal point.
What is optical center in lense?
The optical center of a lens is the physical center point of the lens where light rays passing through it converge without any deviation. This point is important in determining the optical axis of the lens and is often used as a reference point in lens designs and calculations.
