Edmund optics aberrations
Astigmatism is a function of field angles. To summarize, astigmatic aberration occurs when a lens must perform over a wide field, but the performance in the direction of the field is reduced compared to the performance orthogonal to the field (either sagittal or tangential, respectfully). If one looks at a series of bars … See more Spherical aberration refers to rays focusing at different distances depending on where they interact with the lens and is a function of aperture size. To describe spherical aberration, … See more Field curvature (Figure 4) is the aberration that describes the amount in which the image plane curves due to the curvature in the lens design. This … See more A type of chromatic aberration, chromatic focal shift describes how different wavelengths focus along different longitudinal positions (along the optical axis). The goal of most imaging lens designs is to have all … See more Light of different wavelengths focuses at different points since the refractive index of glass varies based on the wavelength of light. Lenses using … See more WebThe individual aberrations are: spherical, field curvature, coma, astigmatism, and distortion. Each one of these optical errors affects a lens’s MTF in a different way, which will be explained in detail later, as will how …

WebEdmund Optics features the world’s largest inventory of off-the-shelf Optical Components, including a wide selection of Optical Lenses, Optical Filters, Optical Mirrors, Windows, Prisms, Beamsplitters, or Diffraction Gratings. Optical Lenses are designed for focusing or diverging lighting. Webwhere Dw[r, q] is the mean wavefront opd, and a[n], b[n,m], and c[n,m] are individual polynomial coefficients. For a symmetrical optical system, the wave aberrations are symmetrical about the tangential plane and only even functions of q are allowed. In general, however, the wavefront is not symmetric, and both sets of trigonometric terms are ...

WebIf your application requires you to reduce the amount of aberrations present in a standard spherical lens, Edmund Optics ® can also modify one of our standard spherical PCX lenses into an aspheric lens.
WebThe minimum spherical aberration occurs when the ray is bent equally at both interfaces. While the first surface of a germanium meniscus lens causes light to bend slightly more than a comparable PCX lens, the second surface of a PCX lens causes light to bend significantly more, resulting in an overall increase in spherical aberration.
