“…Optical systems are built using spherical, conic sections of revolution and aspherical surfaces [35,36]. Conic sections of revolution surfaces, just like spherical surfaces in Young's points, possess rigorous stigmatic points where the system is free from aberrations [37].…”

Among the main defects present in optical systems are geometric aberrations, which are well characterized for spherical and aspherical surfaces. Special cases of aspherical surfaces are the Cartesian surfaces since they exhibit rigorous stigmatism and also, for a subfamily of these surfaces, aplanatism. However, for objects outside the stigmatic points, these surfaces also present geometric aberrations, so to evaluate their performance, it is necessary to characterize them. Therefore, in this work, the geometrical aberrations presented in Cartesian surfaces are studied, where the formulation of the coefficients for primary aberrations includes the corresponding expressions for the conic sections of revolution refractive surfaces as particular cases, and likewise the spherical refractive surface.

“…Consequently, not all of the beam will be focused on a single point, being refracted beyond the focal plane. When spherical aberration is eliminated using specic optical elements, both the laser beam falling near the edge of the lens and the one falling close to the optical axis will be refracted to a single point in the focal plane, 32 as illustrated in Fig. S2b.…”

“…However, perhaps it can also be assumed that in most practical situations involving signal detection (as opposed to image formation), a lens used for flux collection need not be very well-corrected for aberrations. For example, the lens may be a simple commercial off-the-shelf (COTS) singlet with spherical surfaces, which possesses finite residual aberrations [27], even if stop-shifting is an added variable [28]. Such lenses-especially if they are not aspherical-are often not aplanatic, but they may not have significantly high aberrations (at least, not to the point where one would require modifying the object's size to satisfy SSF conditions for signal detection).…”

Textbook chapters on the subject of optical radiometry often impose the condition of aplanatism when deriving a well-known expression for image irradiance in optical systems, yet at least two authors (including this author) have shown that such a condition is unnecessary for the expression to hold. In this paper, theories and computer-aided ray-tracing analyses are provided to support the validity of the expression for even wider cases, where stigmatism, aplanatism, and isoplanatism are all not assumed. Further, it is shown that when both diffraction and aberrations are involved, one may apply a fusion of the expression with the fundamentals of image formation by convolution (if the image is isoplanatic) or superposition (if the image is not isoplanatic) in Fourier optics. To highlight how graduate students and researchers in the laboratory can benefit from the concepts presented here, a practical application is discussed involving signal detection.
