Lot 7 sheets 5 x 7 inches AR coated anti-reflective glass photo picture framing

Description

Lot of seven 5" x 7" AR-coated glass plates.  They look unused, and were stored with thin protective paper between each plate, and wrapped with the label as seen in photo #3.
I suspect Dad bought a 10-pack of these glass plates for framing pictures, and didn't use them all.  He wouldn't have wanted uncoated plate glass for his photos.
These plates come from Dad's garage.  Dad was an optical engineer who worked with lasers, and collected a lot of neat stuff.
I'm happy to combine shipping on multiple purchases.  Please do check out my other listings!
Thank you for looking!
