Meduza Photometric Toolset is an application used to open, view, and evaluate the most common file formats used in photometry.

Meduza Photometric Toolser can handle IESNA LM-63 and EULUMDAT file formats. These file formats are text documents that are easy to read with e.g. Windows Notepad, but requires a complex application to display and evaluate them. The application is designed to perform this tasks.
