what is ma filter

What's the MA filter? I don't know.

AR means Anti-reflecting.

Anti-reflecting filter is used to reduce reflection and enhance transmission.It's idea for optical window use. AR coatings are often crucial components in optical systems with multiple lenses or other optics where the maximum possible light energy is needed. AR coatings help to produce brighter images. AR coatings also reduce the intensity of ghost images which are sometimes produced in optical systems by multiple reflecting surfaces.

differentiate between ma model and ar model

Additionally
AR model performs better for the signals with sharp peaks in PSD, whereas MA modek performs better for the signals with wide lobes in PSD.
