The present invention is directed to cable-less photopolymerization dexterity charging station for curing the photopolymerizable dental material, photopolymerization instrument, in particular contains accumulator for current, such as a storage battery or a capacitor cage, the charging station, contains at least one electrically conductive charge contacts, when the optical polymerizer is connected to the charging station via the charging contacts, the opposite charge contact of the conductive light polymerizer accumulator is charged electrically conductive connection is achieved. Conductive charge contacts are part of an attachment which is fixed or be fixable releasably to the charging station, if the attachment is fixed to the charging station, the charging contacts of the electrically conductive attachment, charging station and it is conductively connected to the second charging contact of the at least one electrically conductive. The present invention also is directed to cableless photopolymerization device for curing the photopolymerizable dental material, the optical polymerization vessel has particular includes accumulator for current, such as a storage battery or a capacitor, photopolymerization instrument, includes at least one electrically conductive charge contacts, when the optical polymerizer is connected to the charging station via the charging contacts, the photopolymerization dexterity of the conductive charging station is capable of electrically conductive connection is formed between the counter charging contact, this by accumulator is charged. Charging contacts of the electrically conductive is a part of the attachment being fixed or be fixable releasably to the optical polymerization reactor, if the attachment is secured to an optical polymerization vessel, charging contact of the electrically conductive attachment but it is conductively connected to the second charging contact of the at least one electrically conductive light polymerizer.
