This film target is intended to be used in the evaluation of digital microfilm scanners for 35 mm preservation microfilm formats. It is available either as a single four-frame chop of 7½” or the same size chop spliced into a 35 mm spool with 6 ft. of leader and 6 ft. of trailer attached.
- Consistent with preservation microfilm, it has a nominal background density of 1.00 and its features fill the entire 35 mm film width
- Individual frames are 35 mm x 45 mm
- Provides for the measurement of Spatial Frequency Response (SFR), resolution, macro/micro distortion, and grayscale behavior over a 0.10 to 1.20 optical density range when used with the supplied software (Windows-compatible)
- Microfilm Preservation Software: Free MScan (Windows) software is available in our Software section.
