inngrodd
Inngrodd is a type of cylindrical, focal lens used in astronomical telescopes, primarily employed in monochromatic imaging. This optical instrument is designed to correct for aberrations in images, particularly those associated with off-axis beam profiles. In contrast to corrective lenses used in shades or eyeglasses, Inngrodd lenses are typically much shorter in focal length, which is a result of the strong focusing application.
The primary purpose of Inngrodd lenses is to compensate for image distortions and spherical aberrations, caused
Inngrodd lenses are well-suited for shell-form aberrations, a notable problem in stellar and chromatic lighting objects.
In usage, Inngrodd focal lenses and beam can increase spectral dispersion of presumably conserved edge density
