For Sale Fresnel Lens for 4x5 GRAFLEX Graflok Fresnel lens for Graphic Cameras NEW old stock

[laser]

Original GRAFLEX part. Like many Graflex optical items they were actually made by Apparatus and Optical Division of Eastman Kodak Co. Both companies were located near Rochester NY. <p>
It is uniform, neutral and quite clear.

Absolutely new. From old stock (1970's) that I have had for years. Excellent condition. Has not been out of the original box until I decided to list on eBay. There may be tiny marks on the edges. This is how they are new. When placed in the ground glass mounting the edges are masked out. The box is NOT included. I need it for the one I am keeping for myself.
The Fresnel places the ground glass in the proper location for focus and BRIGHTENS the screen significantly. The bright screens on Graphic, Linhof, Sinar, Wista, Toyo and other ground glass viewing cameras uses the same type of material. It may fit these cameras but I do not know what size they require. See size below.
Color and clarity are EXCELLENT!

Size: 3 15/16 x 4 13/16 inches, thickness .075 inch. Focal length about 6 inches.
$69 including shipping to USA address. I have a few left. When they are gone they are gone.
