• Anastigmatism — An ideal optical property or characteristic of a lens or mirror system being completely free from astigmatism; the absence of asymmetric focusing distortions, allowing oblique light rays passing through the system to converge into a single precise focal point. This structural phenomenon guarantees uniform sharpness and an exceptional flatness of the image across the entire surface of the projection plane, eliminating marginal blurring.
• Throwers — The plural form of the noun 'aruncător' (devices, weapons, or machineries designed to propel or expel projectiles, flames, grenades, or other objects at a distance); it can also function as a plural feminine adjective to describe entities, forces, structures, or substances that have the property or function of throwing, launching, or scattering elements into space.
