Polar Electro Oy (commonly known as Polar) is a Finnish manufacturer of sports training computers, particularly known for developing the world's first wireless heart rate monitor. [ 1 ] The company is based in Kempele , Finland and was founded in 1977.
The last of the non-avian dinosaurs died 66 million years ago in the course of the Cretaceous–Paleogene extinction event, whereas the earliest members of the genus Homo (humans) evolved between 2.3 and 2.4 million years ago. This places a 63-million-year expanse of time between the last non-avian dinosaurs and the earliest humans.
When the magnetization vector is perpendicular to the reflection surface and parallel to the plane of incidence, the effect is called the polar Kerr effect.To simplify the analysis, and because the other two configurations have vanishing Kerr rotation at normal incidence, near normal incidence is usually employed when doing experiments in the polar geometry.
Luckily, the Quest 3 is still on the way, and most estimations point to a late 2023 release date, with a much-more-reasonable price tag of around $300-$500. Once you set up your Oculus Quest 2 ...
NOBLEX E-Optics GmbH, formerly Docter Optics, is a German manufacturer of optics, including binoculars, rifle scopes, spotting scopes, red dot sights, flashlights and reading glasses. Its headquarters are in Eisfeld, Thuringia, Germany, where most of the products are developed and manufactured. Docter is part of the Analytik Jena Group. [1]
Photometry is a branch of optics that deals with measuring light in terms of its perceived brightness to the human eye. [1] It is concerned with quantifying the amount of light that is emitted, transmitted, or received by an object or a system.
Consider the case of interaction of two perpendicularly polarized waves in nonlinear media with cubic nonlinearity. [1] The equations describing the self phase modulation of the fundamental wave A and the generation of new wave perpendicularly polarized wave B in condition that |B| << |A| (i.e. when the depletion of the fundamental wave is neglected, self and cross phase modulation of wave B ...
[2] In 1935 Land negotiated with American Optical Company to produce polarized sunglasses. [3] Such glasses could screen out glare rather than simply darken the landscape. Land and Wheelwright contracted to begin production of Polaroid Day Glasses, a longtime source of revenue for Polaroid. [4]
