An .LDT file, also known as the ZENAX Source EULUMDAT, is a data file that is used by ZEMAX software. The software is used by optical engineers to design lens, illumination, optical design, laser beam propagation, and other photometry data. The LDT file contains measured photometry data for real lamps that is supported in EULUMDAT format, and the LDT files are used by the Source EULUMDAT file objects in non-sequential mode.
We hope we helped you solve the problem with the LDT file.

There can be more reasons which determine that you are not able to open the LDT file (apart from the lack of the proper application installed).
First - the LDT file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the LDT file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the LDT file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the LDT file has not been completed and it cannot be opened properly).
