Parameters of a Rough Mirror Surface

General

Absorption

In Absolute absorption box, you must type an absorption value in percent.

Reflection

In Relative lambertian reflection box, you must type a Lambertian reflection value in percent.
In Relative gaussian reflection box, you must type a gaussian reflection value in percent.
In Gaussian angle (FWHM) box, you must type a gaussian reflection angle value in degree.
FWHM angle (Full Width at Half Maximum) is used as following.

Note: Following relations between the various parameters are taken for granted: Absolute total reflection + Absolute absorption = 100 Absolute specular reflection + Absolute Lambertian reflection + Absolute Gaussian reflection = Absolute total reflection Relative specular reflection + Relative Gaussian reflection + Relative Lambertian reflection = 100

Incidence Dependency

Incidence (deg)

In Incidence (deg) row, you must type incidence values.

Note: Note that the zero value is for normal incidence.

Relative Absorption (%)

In Relative absorption (%g) row, you must type relative absorption values for each incidence.

Note: This value is relative to the Absolute absorption defined in General tab.

Note: You can Add

or Delete

column.

Wavelength Dependency

Wavelength (nm)

In Wavelength (nm) row, you must type wavelength value in nanometer.

Relative Absorption (%)

In Relative absorption (%) row, you must type relative absorption value for the above illustrated wavelength.

Note: This value is relative to the Absolute absorption defined in General tab.

Note: You can Add
