A branch of science concerned with the study of light
Optics
Optics shows the properties of light as it acts upon by?
Optical systems
Branches of Optics
Geometrical Optics
Physical or Wavefront Optics
Quantum Optics
A phase of optics which treats of the formation of images by light rays
Geometric optics
It includes the study of the influence of plane and spherical mirrors, plane and spherical refractors, thick and thin lenses, prisms, and optical systems upon light
Geometric optics
Uses line diagrams to depict the behavior of light
Geometric optics
The fundamental laws of geometric optics
Law of Rectilinear Propagation
Law of Reflection
Law of Refraction
Uses principles of waves to describe the behavior of light
Physical or Wavefront Optics
Involves primarily in theory of waves
Physical or Wavefront Optics
Theory of Waves
Reflection
Refraction
Absorption
Dispersion
Deals with the interaction of light with the atomic entities of matter and methods of quantum mechanics
Quantum optics
Deals with the clinical application of optics in refraction, instrumentation, and dispensing
Applied optics
Applied optics deals with the clinical application of optics in?
Refraction
Instrumentation
Dispensing
Designed to provide students with the necessary expertise in handling the different types of ophthalmic clinical instruments
Applied Optics
Relevance of each test in coordination with the use and manipulation of the different ophthalmic instruments in he routinary clinical eye examination is given emphasis
Applied Optics
Light coming from a point source
Divergent
Light rays travelling parallel have?
Zero vergence
Light that focus on a point
Convergent
The closer the light to its source, the (greater, lesser) the vergence
greater
The farther the light is from its source, the (higher, lower) the vergence
lower
The vergence approaches zero as vergence goes toward?
Infinity
Unit of measurement of vergence
Diopter
Refracting power of light bending capacity of the lens
