• Designed for MTF Testing
• Determines Image Quality of Imaging Components
Sinusoidal patterns are designed specifically for evaluating the MTF of imaging lenses and other system components. This is
accomplished by analyzing the ability of imaging components to reproduce the contrast of the sinusoidal target. MTF analysis
is necessary when evaluating components to confirm that they meet design specifications and performance expectations.
MTF evaluation is one of the best methods to determine overall image quality, not just absolute limitations. Implementation
of MTF testing procedures can reduce costs by ensuring that neither under-specification nor overspecification occurs. The
advantage of a sinusoidal target is that it relays image quality information over a full range of frequencies instead of only the
maximum obtainable resolution. By using the different frequencies on the target, baselines can be established that directly
relate to system requirements. The grayscales on the target are used as references for denoting the contrast levels of the
sinusoidal frequencies.

• Video Calibration
• Permanent Density Standard
• Evaluate/Compare the Dynamic Range of Cameras
Ideal for evaluation of video or optical inspection systems
and cameras. Convenient format (50.8 x 50.8 x 1.5mm nominal)
may be viewed directly or projected with 35mm slide
projector. Pattern is a “standard” and consists of two scales:
EIA Equal Steps Transmission (Linear) and EIA Equal Steps
Density (Logarithmic). Each scale has nine steps from 3% to
60% T (EIA 20:1). All steps are accurately obtained by an ultraprecise
halftone pattern. Pitch is 0.001". The steps are side-byside,
0.200" x 0.100", without spaces or borders. Transmissions
and Densities are shown below with strict tolerances. Scale is
permanent chrome on glass material which resists harsh environments.
Background is opaque with an Optical Density of
3.0 (T = 0.1%).
