WebNov 17, 2024 · The eye is scanned at the rotated axis which passes through the anterior corneal center and the pupillary center [1]. Advantages are the ability to be performed in the immediate postoperative period and in eyes with corneal opacification, such as from corneal edema, and it also does not need coupling fluid. WebJul 17, 2006 · Now the optical axis is slightly tilted within the telescope tube. In practice, this is not a problem because the tilt is never more than a small fraction of a degree. Since the secondary is offset down the tube, this is known as partially offset collimation.
WebOct 26, 2024 · The paraxial approximation can be used to derive simple equations involving lenses. A statement of the approximation involves the optical axis, which is a line that passes through the center of each lens and is oriented in a direction normal to the surface of the lens (at the center). The paraxial approximation approximation is valid for rays ...
