Corning Optical Filters


A rectangular wooden box with a hinged lid contains 35 glass filters of varying colour and thickness. Most are square with a paper label listing identifying information at the top corner. Inside the lid is a label listing the code number and thickness of 23 filters.

Two unlabelled rectangular filters have a green tint and are slightly radioactive. These are likely of uranium glass and are stored separately.
