What is the center point of lens called?
axis or optical center
What is the optical center of a zoom lens?
If you look through the lens at a distant point, the point image will not move when the lens is rotated slightly about a vertical or horizontal axis the goes through the nodal point. This is called the optical center. With a thin lens this is close to the geometric center, with a longer complex lens the optical center is buried somewhere inside. The optcial center of a complex lens may or may not be inside an element.
Is optical center is same as the geometric center of a lens?
no it is same
What is optical center of lens?
The optical center of the lens is a point on the axis of a lens is the point where any ray passing through this point, the incident part and the emergent part are parallel. It is important for the proper refraction of light.
Where is the optical center of a Kryptok 22 lens?
It's in the centre of a round segment!
A straight line drawn outward from the center of a lens or mirror?
Optical axis. There ya go!
What is optical center of a lens?
optic centre is the geometrical centre of the lens the rays of light passing through this point emerges in the same direction without bending.
A lens that is thicker in the center than at the edges is called a?
Convex lens.
What optical structure do all microscopes contain?
''All microscopes contain the optical structure called a lens.''
Why the a ray passing through center of lens do not bends?
It is because the central portion of the lens i.e. optical centre can be considered similar to a parallel sided glass slab.
Why are CD-ROM and DVD drives called optical drives?
It is called an optical drive because the mechanism for reading and writing information is optical (light) based - it uses lasers.
Does a thinner and less convex lens have a shorter focal length and low optical power?
It is not necessary that a thinner convex lens have less optical power or a thicker lens has more optical power
