Optics Software Downloads

Version 6.0
Released: April 17, 2013

Release Notes:

Only a full installation of this version is available. We recommend downloading and installing Optics 6, as it has a few bug fixes and works with Windows 7 and 8.

It is possible to install and run this version in addition to Optics5.

This version contains Glass Library records from IGDB (Spectral Data) Version 29.0. Check for IGDB updates.

NFRC (National Fenestration Rating Council) will "sunset" use of Optics 5.1 on June 1, 2013, and it will no longer be available for download.

Program Changes

Microsoft Windows 7 / Vista Operating System "Aware"

Optics now installs and operates much better under the Microsoft Windows 7 and Vista operating systems. It is no longer necessary to run the "VistaFix" batch file after installing the program.

Fixed Bugs

Paths Appear in Tools/Options

In the Microsoft Windows 7 / Vista Operating System environments, the program would not display the directory paths in the Tools / Options "File Locations" dialog box. This is now fixed.

Applied Film on Low-E Glass

Optics5 had a bug where an applied film put on an uncoated layer showed the same result as the same film applied to a coated layer. This has been fixed.

If you find bugs, or if you think these have not been fixed, please do not hesitate to send an email to OpticsHelp@lbl.gov to report your findings. Getting feedback from users is how we improve the program.
