Optic distortion
Did you know?
In optics, aberration is a property of optical systems, such as lenses, that causes light to be spread out over some region of space rather than focused to a point. Aberrations cause the image formed by a lens to be blurred or distorted, with the nature of the distortion depending on the type of aberration. Aberration can be defined as a departure of the performance of an optical system from the pr… WebACA, along with other aberrations, can be measured two ways. The first as a distance along the optical axis (longitudinal) and the second as a distance perpendicular from the optical …

Once again, there are two general categories for measuring distortions: Optical and TV distortion. Optical distortion measures the space between where an object appears in a frame versus where it appears in reality, or where it should be.
WebZEISS DIGIGON lenses have been specially designed for dome projection, which is why they project with particularly low distortion on spherical surfaces. Even at the edge of the image, the quality is not affected by chromatic aberration and optical distortion. This ensures that every single pixel contributes to the razor-sharp projection.
