STEEP321 is the program for Monte Carlo calculations of radiation characteristics of axisymmetric blackbodies. STEEP321 uses the Uniform Specular-Diffuse (USD) model of reflection. This is a simple but powerful blackbody modeling tool allowing to calculate entire spectral effective emissivity curve ...

Reflection model Max. number of temperature distributions computed simultaneously Cavity shape This Comparative Table will help you to make optimal choice of the blackbody emissivity modeling software. The right choice is determined by your blackbody calibration sources, complectness of input data, ...

Usually, Fresnel's law is written in its simplified form, for the case when the medium from which a ray falls onto two media interface, is transparent (i.e., its extinction coefficient is equal to zero or very small). However, in some instances (e.g., in photolithography, or in studying the reflecta...

STEEP323 computes spectral effective emissivities and radiance temperatures for an axisymmetric cavity formed by rotation of a non-self-intersecting polygonal line around an axis. STEEP323 is the most powerful blackbody emissivity modeling program to date. It employs the 3C BRDF model, which allows ...
