Hand-ground, bright matte surface. Quite bright even at f/8!

Clarified glass for increased sharpness

Size of ground glass is exactly 8"x10"x0.08"(inch)   |   203x254x2(mm)

45 degree clipped corners with Grid as pictures show.

Matte ground surface is on one side of the glass, the other side is regular glass.

The glass sides are smooth so there is no danger of accidental cut.

Make sure to install the grounded surface on the inside of your camera in order to protect the grounded surface and not have a focus shift upon taking your shot with a film holder.
