(nu), is a measure of how much a fabric contracts during the perpendicular direction due to stretching, or conversely, the amount a material expands inside the route perpendicular to your utilized pressure as a result of its compression. Visualize stretching a rubber band and observing the band come to be thinner; as you carry on to stretch it farther, the thinness also improves.

ZnSe Home windows have a relatively superior refractive index of 2.four, which makes them well suited for use in An array of optical devices and programs. They have a small absorption coefficient, which makes them perfect for use in substantial-electrical power laser systems, the place the windows have to have to stay clear even under superior intensity laser light-weight.
