Interesante articulo para aquellos que quieran familiarizarse con algunos de los parámetros clave del diseño de ópticas para la RV.
Field of View
Material and type of lens
Other characteristics (tamaño, peso, coste, número de lentes,...)
Putting it all together: it is practically impossible to find a car that is inexpensive, has amazing fuel efficiency, offers fantastic acceleration, seats 7 people and is very pleasing to the eye. Similarly, it is difficult to design an optical system that has no distortion, provides wide field of view, large eye box, costs next to nothing and is very thin. When contracting the design of an optical system, it is useful to define all desired characteristics but specify which parameters are key and which parameters are less important.
