WebSep 2, 2024 · We substitute the off-axis parabolic (OAP) surfaces for spherical surfaces of the collimating mirror and each sub-region of the focusing mirror, to achieve an aberration free configuration. The multiple OAP surfaces are then expanded and mixed, to construct a freeform surface integrating the collimating and focusing mirrors into a single element. WebWhen a spherical mirror is used under off-axis conditions, spherical and coma aberrations occur, which cause the degradation of resolution of a spectrometer. Off-axis parabolic mirrors theoretically eliminates these aberrations and ensures high resolution even in a short focal length compact spectrometer.

WebOct 21, 2013 · A parabolic mirror takes light from a point source located at the focus and creates a collimated beam. In other words, a source with spherical wavefronts placed at the parabolic focus is converted into a beam with plane wavefronts. The reverse operation is also true; plane wavefronts incident on the parabolic mirror are focused at the focal point.
