finesse.materials module

Material objects are a simple structure that contain commonly used properties for calculations. By default this includes Fused Silica and Silicon at 123K.

class finesse.materials.Material(alpha, nr, dndT, kappa, emiss, poisson, E, rho, C, T)

Bases: object

dndT

Thermo refractive coefficient \(\frac{dn}{dT} \: [K^{-1}]\)

emiss

Emissivity

kappa

Thermal conductivity \(\kappa \: [W m^{-1}]\)

nr
