| In ] experiments, an '''absorber''' is a block of material used to ] some of the energy of an incident ]. Absorbers can be made of a variety of materials, depending on the purpose; ] and ] are common choices. | |||
| Most absorbers are used as part of a ]. | |||
| A more recent use for absorbers is for ], as in the ]. | |||
| In ], the most important part of the collector takes up the heat of the ] ] through a medium (water + ]). This is heated and circulates between the collector and the storage tank. A high degree of efficiency is achieved by using black absorbers or, even better, through selective coating. | |||
| In ], ingredients which absorb UVA/UVB rays, such as ] and ], are known as absorbers. They are contrasted with physical "blockers" of UV radiation such as ] and ]. | |||
