WebWe offer the general configuration and design of an aplanatic optical system consisting of a single aspherical lens and its entrance pupil. The aspheric lens is aplanatic for three-point objects and their respective three-point images when the three-point objects are very far away from the singlet. WebThe Simultaneous Multiple Surface (SMS) method in planar geometry (2D) is applied to imaging designs, generating lenses that compare well with aplanatic designs. When the merit function utilizes image quality over the entire field …

WebThis paper presents a distortion correction method for designing a wide field of view (FOV) lens for an imaging system. The lens is composed of two aspheric surfaces and several spheres. In the preliminary design, profiles of the aspheric surfaces can be obtained according to aplanatism, refraction law, and polynomial fitting methods, where the … WebThe usual aplanatic imaging (axial stigmatism and fulfilment of the sine condition) means an ideal aberrationfree imaging in an approximation being linear in regard to the dependence on the off-axis distance of an object point [1,2]. The degree of this approximation can be improved by aplanatism of higher order [3]. m th order aplanatism means that the wave …
