* list covers only a selection of infrared lenses available. Thermosensorik GmbH can accommodate individual customer requirements.
** In all infrared lenses, the macro limit can be further reduced by using adapter rings without serious loss of imaging quality. Owing to the shorter distance to the lens, adapter rings capture a smaller section of the object.
