The 2 m subtense bar from Zeiss Jena is a 2 piece light metal tube which you can stuck together via a screw flange. The ends of the tube have targets at exactly 2 m separation. They can also be illuminated ellectrically with a illumination set. You will receive also the illumination set, but accumulator (storage battery) is unfortunatelly NOT a part of the set. The small lamps were normally equipped with small 2,5V 0,2A bulbs. Inside each half of the rod there is an invar bar for temperature compensation. Invar (nickel-iron alloy) is unique in its resistance to the temperature changes, so unlike other metals it will not expand or contract (it is from word invariable). Subtense bar is also called parallactic bar, because it was used as a base by measuring parallactic angle with precision theodolites, like for example Theo 010. Once all is set up, observer will measure the angle from his position to each end of the 2 m markings on the subtense bar, do some calculations and he will get the distance from the observer to the centre point of the bar.
