Resolution and Contrast Comparison
This is Section 7.3 of the Imaging Resource Guide
High levels of optical performance are critical for successful imaging solutions. Edmund Optics® has taken care to maintain optical performance across the entire image plane. Resolution and contrast typically deteriorate at the corners of an image, thus both the center and corners of an image must be considered when comparing overall lens performance.
Shown below are comparisons of our TECHSPEC® C Series Fixed Focal Length Lens at the center and at the corner of the images to the performance of various competitor lenses. Edmund Optics® lenses show a 30% increase in contrast over the closest competitor at the center of the image. Additionally, Edmund Optics® lenses show over twice the contrast in the corner making our Compact Fixed Focal Length Lens ideal from the most simple to the most complex applications. All tests are done with a 16mm lens at f/2 on a 1.3MP, ½” sensor camera and 1.5” field of view
