I proiettori per teatro e le loro lenti

Theater projector lenses can be PC or Fresnel. Here are the differences: Plano-Convex Lens: This lens has a flat and a convex surface. It is used in theater lights to concentrate light into a precise and defined beam. It offers intense, directional illumination, ideal for sharp effects, such as those of profile spotlights. Fresnel Lens: The Fresnel lens is characterized by a series of concentric rings that reproduce the effect of a convex lens, but with less material and weight. It produces a softer, more diffused light, with soft edges, and is perfect for mood lighting or for covering large areas with uniform light.
