I try to model the filter coating according to data from https://www.idex-hs.com/store/product-detail/ff750_sdi02_25x36/fl-007128 The table I include to the coating file is attached. ZEMAX says that this is a bad coating (nonsec. mode, NSC shaded view window). The filter is tilted y to -45 degrees relative to the incidence collimated beam of multiple wavelength from the range of 671-930 nm). I try to use the angle in the table 45, -45 and 135. The result is the same - bad filter. Please, tell me what is wrong in my filter model (attached file).

The coating file is sensitive to formatting, so I would recommend opening your file in a text editor like Notepad++ and compare your format against the COATING.DAT file that is provided with OpticStudio.
I did it and we can see differences in terms of data separators and also you are missing Ars Arp Ats Atp at the end of your lines:
I have made the format modifications and now it works:
I have attached the modified file.
Thank you very much, your file works.
