LT202L的激光发射系统具有200米的有效射程（白天），光斑大小为5mm/100m，且激光束聚集时光斑中心与望远镜视准轴偏差不超过5秒。其激光电源为DC3V，由2节AA电池供电。仪器整体设计紧凑，尺寸为153×175×360mm，重量为4.5kg，适合在各种环境下使用。
English Introduction
The Suzhou Guang Electronic Theodolite LT202L is a multifunctional precision measuring instrument widely used in engineering surveying, construction, industrial inspection, and other fields. Based on the traditional electronic theodolite, this model has been enhanced with a laser emission system, providing laser guidance capabilities. The laser system uses a 635nm semiconductor laser emitter, with the laser beam coaxial and confocal with the telescope s sighting axis, offering clear laser guidance for construction projects.
In terms of angle measurement, the LT202L employs a photoelectric incremental method with a minimum reading of 1 arcsecond and a measurement accuracy of 2 arcseconds. The telescope features a 45mm objective lens aperture and a 30x magnification, with a field of view of 1°30′, making it suitable for various measurement scenarios. Additionally, the instrument is equipped with an automatic vertical compensator with a compensation range of ±3′, ensuring accurate measurements.
The laser emission system of the LT202L has an effective range of 200 meters (in daylight), with a spot size of 5mm at 100 meters. The deviation between the laser spot center and the telescope s sighting axis is no more than 5 arcseconds. The laser power supply is DC3V, powered by two AA batteries. The instrument is compact in design, with dimensions of 153×175×360mm and a weight of 4.5kg, making it suitable for use in various environments.
