Hyperchromatic lens

WebThe hyperchromatic lens system incorporates a combination of diffractive and refractive components to maximally separate focal position as a function of wavelength. A method and apparatus for the capture of a high number of quasi-continuous effective frames of 2-D data from an event at very short time scales (from less than ... Web22 dec. 2024 · Subsequently, placing lenses L 3 and L 4 to face L 1 and L 2 symmetrically would notably diminish the vertical axis aberration, such as distortion. The vital step to correct the chromatic aberration is through replacing the negative meniscus lenses L 2 and L 3 with hyperchromatic lenses L 21, L 22 and L 31, L 32, respectively.
