Abstract: An apparatus for making a beverage including an infusion chamber for a capsule containing a food substance, an insertion opening for inserting the capsule into the apparatus, a transfer channel for transferring the capsule from the insertion opening to the infusion chamber, an image acquisition device to acquire at least one image of a portion of the capsule. The image acquisition device includes an optical sensor facing an image capture zone in which, in use, said capsule is located or passes. A viewing window, made of transparent material, is interposed between the optical sensor and the image capture zone. A heating element for heating the viewing window is applied to, or incorporated in, the viewing window.

Abstract: This invention relates to an apparatus (1) for making a beverage, comprising an infusion chamber (21) suitable for receiving a capsule containing a food substance for making a beverage, an insertion opening (31) for inserting the capsule into the apparatus (1), a transfer channel (32) for transferring the 5 capsule from the insertion opening (31) to the infusion chamber (21), an image acquisition device (4) which is intended, in use, to acquire at least one image of a portion of the capsule. The image acquisition device (4) includes an optical sensor (42) facing an image capture zone (40) in which, in use, said capsule is located or passes. The apparatus (1) further comprises a 0 viewing window (45), made of transparent material, which is interposed between the optical sensor (42) and the image capture zone (40). The viewing window (45) has a first face (451) facing the optical sensor (42) and a second face (452) facing the image capture zone (40).
