Target Grid Distortion on Film

Useful for measuring Video System distortion. Known dot diameters and spacing used to quantify Image field Actual distances versus Predicted distances. Corrections result for image processing or direct readings.

Pattern: Five (5) square dot arrays on 8” X 10” white film.
(1) Dot spacing: 6.00mm. Dot dia.: 3.00mm. Square length (center to center): 150.00mm
(2) Dot spacing: 3.00mm. Dot dia.: 1.50mm. Square length (center to center): 102.00mm.
(3) Dot spacing: 1.50mm Dot dia.: 0.75mm. Square length (center to center): 72.00mm.
(4) Dot spacing: 1.00mm. Dot dia.: 0.50mm. Square length (center to center): 48.00mm.
(5) Dot spacing: 0.50mm. Dot dia.: 0.25mm. Square length (center to center): 24.00mm.

Material: White film with black emulsion dots for high contrast. Includes N.I.S.T. Traceable Certificate of Accuracy.
