In 2016, we added our dazzling new DFML Grade diffuser film to this line of optical films. It’s a film substrate designed to stretch bright point light sources to the MAX in an asymmetric pattern. That’s why we call it Asymmetric Diffuser Film.

Field curvature (a.k.a. Petzval field curvature) results because the focal plane is actually not planar, but spherical. Spherical aberration occurs in a spherical lens or mirror because these do not focus parallel rays to a point, but instead along a line. Therefore, off-axis rays are brought to a focus closer to the lens or mirror than are on-axis rays.

Coma occurs because off-axis rays no not quite converge at the focal plane. Coma is positive when off-axis rays focus furthest from the axis, and negative when they are closest. Distortion is caused because the transverse magnification may be a function of the off-axis image distance. Distortion is classified as positive (so-called pincushion distortion), or negative (so-called barrel distortion). Field curvature (a.k.a. Petzval field curvature) results because the focal plane is actually not planar, but spherical. Spherical aberration occurs in a spherical lens or mirror because these do not focus parallel rays to a point, but instead along a line. Therefore, off-axis rays are brought to a focus closer to the lens or mirror than are on-axis rays.

Astigmatism occurs in lenses because a lens has different focal lengths for rays of different orientations, resulting in a distortion of the image. In particular, rays of light from horizontal and vertical lines in a plane on the object are not focused to the same plane on the edges of the image. Chromatic aberration occurs in lenses because lenses bring different colors of light to a focus at different points. Coma occurs because off-axis rays no not quite converge at the focal plane. Coma is positive when off-axis rays focus furthest from the axis, and negative when they are closest. Distortion is caused because the transverse magnification may be a function of the off-axis image distance. Distortion is classified as positive (so-called pincushion distortion), or negative (so-called barrel distortion). Field curvature (a.k.a.

An optical aberration is a distortion in the image formed by an optical system compared to the original. They can arise for a number of reasons having to due with the limitations of optical components such as lenses and mirrors. Astigmatism occurs in lenses because a lens has different focal lengths for rays of different orientations, resulting in a distortion of the image. In particular, rays of light from horizontal and vertical lines in a plane on the object are not focused to the same plane on the edges of the image. Chromatic aberration occurs in lenses because lenses bring different colors of light to a focus at different points. Coma occurs because off-axis rays no not quite converge at the focal plane. Coma is positive when off-axis rays focus furthest from the axis, and negative when they are closest.
