What is the cardinal point of optical system?
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.
What does the angle of parallax determine?
Accuracy of readings of e.g. meters and certain optical instruments. Parallax is also used in astronomy for calculating distances to(astronmically)far-away objects.
What is bak-4 prism?
BAK-4 prisms are the best; they are made of superior optical glass that produces clearer images. BAK-4 prisms show a truer round, which translates to better light transmission and edge-to-edge sharpness. These are what you want in your binoculars.
What is an analyser in a polariscope does?
In a polariscope, an analyser is a critical component that works alongside the polarizer to analyze the light transmitted through a sample. The primary function of the analyser is to determine the optical properties of materials by measuring the intensity and nature of polarized light after it has interacted with the sample. Key Functions of the Analyser in a Polariscope: 1. Polarized Light Analysis: The analyser allows for the examination of light that has been altered by the sample. It can be rotated to change the orientation of the polarized light, enabling the user to observe variations in light intensity, which indicates the material's optical characteristics. 2. Determining Optical Activity: In substances that exhibit optical activity (such as certain liquids and crystals), the analyser helps measure the degree of rotation of polarized light caused by the sample. This property is essential in fields like chemistry and materials science for identifying substances and determining their concentrations. 3. Stress Analysis: In materials testing, particularly for transparent plastics and glass, the analyser can reveal internal stresses and strain patterns by showing color variations or fringes when viewed under polarized light. This information is vital for quality control and assessing the structural integrity of materials. 4. Characterizing Material Properties: The analyser aids in characterizing various material properties, such as birefringence, which is the difference in refractive indices in different crystallographic directions. This is useful in identifying material types and assessing their suitability for specific applications.
Does optical insurance cover disposable contact lenses?
If you were to purchase optical insurance, you would have to pay an increased rate for a preexisting condition. However, the optical insurance would cover the cost of of the lenses.

Why high concentration HAVE high optical density?
High concentration of a substance leads to high optical density because more particles are present in the solution, resulting in increased scattering or absorption of light. This increased interaction with light causes a greater reduction in light intensity, making the solution more opaque and resulting in higher optical density.
What tools would help you determine the source of either of these problems?
optical time domain reflectometer
Is it the eye or the brain that sees the optical illusion?
It is the brain that has problems in interpreting apparently contradictory inputs from the eye.
How does optical density of a medium affect the speed?
The optical density of a medium, determined by its refractive index, affects the speed of light passing through it. Light slows down when moving through a medium with a higher optical density. This change in speed is caused by the increased interactions between the light and the atoms in the medium.
What has the author Helmut Dosch written?
Helmut Dosch has written: 'Critical phenomena at surfaces and interfaces' -- subject(s): Critical phenomena (Physics), Grazing incidence, Neutrons, Optical properties, Scattering, Surfaces (Physics), X-rays
How has using optical fibers made an impact of survival rate on surgical problems?
Optical fibers make an impact because it needs to be thick enough so the surgery van be easier which controls the rate
What is a circular polarized filter?
It provides high quality optical glass for increased clarity and limits reflection from nonmetallic surfaces and picture washout.
What type of zoom results in increased magnification without a change in image quality?
Optical zoom results in increased magnification without a change in image quality because it physically adjusts the lens to zoom in on an image. This is different from digital zoom which enlarges the pixels of an image resulting in reduced image quality.
