- Understanding Lenses: Aplanats and Achromats - Photonics
Aplanatic lenses are designed to produce the minimum focal spot size at a particular wavelength by eliminating coma and spherical aberrations They are usually air-spaced and can have two, three or four lens elements made from one or more glass materials
- What do aplanatic optics do? - Celestron
Aplanatic optics are designed to eliminate both spherical aberration and coma, two major aberrations (image defects) found in telescopes The end result is sharper images across a much wider field of view than in other designs
- APLANATIC Definition Meaning - Merriam-Webster
The meaning of APLANATIC is free from or corrected for spherical aberration How to use aplanatic in a sentence
- Aplanatic lenses revisited: the full landscape - Optica Publishing Group
The full scope of solutions for dual-contour aplanatic lenses that can approach the basic limit for radiation transfer are identified, analyzed, and illustrated Complementary solutions are shown to yield lenses that are either monolithic or have two refractive contours separated by an air gap
- What do aplanatic optics do? - GigOptix
Aplanatic optics, however, are a much-upgraded version of SCT optics They focus on the corrector plate to clear the aberrations The corrections are made from a tiny area closer to the centre of your field of view Aplanatic optics is a valuable asset for astronomers
- Aplanatic - Stellar Astronomy
To create an aplanatic system, a clever combination of lenses with carefully chosen shapes, materials, and positions is required This intricate design effectively cancels out the unwanted aberrations, producing a sharper, more accurate image
- Aplanatic lenses, aplanatic points, and aplanatic conditions
The aplanatic lenses (aplanats), which can in some cases be condenser or objective lenses, are free of spherical aberration and off-axial coma simultaneously The images fomred by the aplanatic lenses displays an extremely high contrast
- What does aplanatic mean? - Definitions. net
Aplanatic refers to a lens, mirror, or optical system that is free from or corrected for spherical and chromatic aberration, thus effectively reducing distortion and presenting a clear and accurate image
