Transmission vs Thickness Calc

This program allows for calculation of internal transmission loss through transparent materials at varying thicknesses (Beer Lambert's Law) while compensating for first and second surface reflectance losses (calculated as a function of material refractive index [ND20]). The calculations within this program assume light entry normal to materials surface. The calculations within this program also assume parallel material surfaces on both faces of the transparent material.
Future versions of this program will allow for this calculation to be carried out at varying entry angles.
