What is DR glass unit?

[plhoward]

Hey there - I recently just had my X-T4 cleaned and repaired by Fuji. I had this annoying spot on all my images, regardless of lens and cleaning sensor multiple times. Good news is they were able to fix the issue. In the notes they said "Replace DR glass unit. Inspected and cleaned."

I'm trying to figure out what they mean by DR unit? I'm guess DR is for "dynamic range" but I was hoping to search on the interwebs for some diagram as to where that unit exists in the camera. I'm just curious and love to learn how things operate and are built. If anyone has any info I'd appreciate it.

I'm just happy to have my camera back and fully functional. Though bummed they removed the hidden battery and had to re-program the camera to my settings.

In this case it‘s most probably just a part‘s name. You would need a service manual to look parts up, but these are not publicly available as far as i know.
