Aberration: a departure from the paraxial limit.. Paraxial limit: (1) Rays are kept close to the optic axis.. . (2) Small angle approximation (1. st. Order). 5. th. Order. . 3. rd. Order. Chromatic Scale . A scale made completely of half steps. 13 notes. Starts and stops on the same note name. Use sharps going up (higher). Use flats going down (lower). Chromatic Scale (higher). The following steps will always get you the correct answer.. ‘s law:. n. 1. sin. θ. 1. = n. 2. sin. θ. 2. Refractive index depends on wavelength of light (color). With different refractive indices, colors are . dispersed. Chromatic aberration. To generate a sharp image, light must converge at the same point.. Module . 7. Panoramic Photography . is a technique that captures images with elongated fields of view. . This generally means a photo measures a . ratio of 2:1 or larger, . the image being at least twice as long as high.. L*=1.5m CEPC . I. nteraction Region. Yiwei. Wang, . Dou Wang, . Sha. Bai.

Often we want to image (and measure) the location of different color proteins inside cells. XY registration is easy, but it is not so simple in Z.. . But not ideal!
