coefficient of thermal expansion of wpc belize

An Introduction to Passive Athermalization Edmund Optics

Thermal Defocus. The expansion and contraction of a material due to temperature changes is governed by a material’s coefficient of thermal expansion α which has units of 10 -6 m/ C or ppm/ C . The change in length L of a material due to a temperature change is given by Equation 1.

Thermal expansion - Wikipedia

Thermal expansion is the tendency of matter to change its shape area volume and density in response to a change in temperature usually not including phase transitions.. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated molecules begin to vibrate and move more usually creating more distance between themselves.
