A spherical lens and an axicon are combined to form an optical system producing a ring-shaped focalization pattern. The diameter of the ring in the focal plane depends on the angle of the axicon, on its dielectric index, and on the focal length of the spherical lens. The diffractional ...

Spherical ShellsWe have theoretically investigated the problem of electromagnetic diffraction by a wide-angle spherical mirror receiving obliquely incident plane waves of linearly polarized monochromatic radiation. The Debye-Picht- Luneburg-Wolf integral representation of the diffracted field has been applied ...
Mirrors: Difference Between Plane & Spherical from Chapter 15 / Lesson 1 86K A mirror surface can produce clear reflections due to its smooth surface. Explore the difference between the two types of mirrors, plane and spherical, and the problem with aberratio...
We derive a formulation that can be used to determine the electromagnetic field distribution in the focal region of a wide-angle spherical mirror illuminated by an obliquely incident and linearly polarized plane monochromatic wave. The integrals representing the diffracted fields derived in part 1 [1...
A concave mirror of focal length f, in air, is immersed in water of refractive index43. The focal length of the mirror in water will be View Solution The focal length of spherical mirror is View Solution Focal length of a plane mirror is ...
Give one condition when concave mirror does not form a real image. Answer: When the object is placed between the focus and pole of the concave mirror, the image formed is virtual.Question 6: Convex mirror is a diverging mirror so it does not form a real focus. But plane mirror is not...
Have you ever done this evaluation for an optimal mirror position / back focus - do you have an opinion about it? Was the combination of C8 plus Correctors insufficient for full-frame camera sensors? This has been a topic of interest for me, so thank you Porkkala, whatever you decide. ...
A spherical mirror produces an image that is located 43.0 cm behind the mirror when the object is located 12.5 cm in front of the mirror. a. What is the focal length of the mirror? b. Is this mirror concave or convex? Some telephoto ca...
Following a classical approach of Fourier optics, it was concluded that the back focal plane of the spherical lens displays the Fraunhofer diffraction pattern of the field that exists in the first principal plane of the relay lens (z=−Rsph, Figure 17.3). In the present case, since the le...
