The best image quality is provided by a convex-concave meniscus lens with its convex side facing the photosensitive layer and with a diaphragm located in front of the objective. Monocles have a small aperture ratio (not exceeding 1:8) and a small image angle (not exceeding 25°). A monocle is also called a landscape lens.
