NFRC now has a procedure for making laminates in Optics5 and importing those laminate constructions into WINDOW5 to be used in a whole product calculation.

The information presented below is provided to help simulators with this process. Feel free to contact us at WINDOWHelp@lbl.gov with questions or comments.

Help and Troubleshooting

Bug with Coated Substrates
In Optics 5 (version 5.1 Maintenance Pack 2) the program does not calculate the correct results for applied films on coated substrates -- it calculates the same result as the applied film on a non-coated substrate.

Example: 

Uncoated substrate with Applied Film:

• Layer #1 = CLEAR-3.LOF
• Add Applied Film = Southwall VK75.swt  (V-Kool 75)

Coated substrate with Applied Film:

• Layer #2 = LOW-E_3.LOF
• Add Applied Film = Southwall VK75.swt (V-Kool 75).

All the Transmittance and Reflectance values are identical for both new layers, which is not correct.
