Environment Manager gives you an opportunity to design a coating for several environments simultaneously. For each environment it is possible to define different Targets, Color Targets, Light Sources, Detectors, Incident Media, Substrates, the state of Back Side, Substrate Thickness, and the presence of Back Side coating. Also it is possible to define different materials for the same index abbreviation. 

Example: design anti-reflection coatings in the visible spectral range for three different substrates (B270, BK7 and Suprasil) and three different light sources (D65, D55 and CIE STANDARD A). High index materials are also different. 

Anti-reflection design settings for three different environments.

Reflectances of each of three designed anti-reflection coatings

In the course of the design process the resulting merit function value is determined by formula:

\[MF_{total}^2=\frac 12 \cdot (MF_1^2+MF_2^2+...MF_{Nenv}^2)\]
