苏光电子经纬仪LT202L苏州一光激光电子经纬仪 双激光
中文介绍
苏光电子经纬仪LT202L是苏州一光推出的一款双激光电子经纬仪，它在传统电子经纬仪的基础上增加了激光发射系统，具备多种功能，能够满足不同场景下的测量需求。
该仪器的电子经纬仪部分采用光栅增量式数字角度测量系统，结合微型计算机技术，可实现测量、计算、显示、存储等多项功能。其角度测量精度达到2″，最小读数为1″，能够满足较高精度的角度坐标测量和定向准直测量需求。
其望远镜物镜孔径为40mm或45mm，放大倍率为30倍，视场角为1°20′或1°30′，最短视距为1.3m或2m，视距乘常数为100，视距加常数为0。
激光发射系统采用635nm半导体激光发射器，激光与望远镜照准轴同轴、同焦，有效射程在白天可达200m，光斑大小为5mm/100m，激光束聚集时光斑中心与望远镜视准轴偏差不超过5″。
此外，该仪器还配备了双面显示屏、分划板、照明系统等，方便用户在不同环境下进行操作。
苏光电子经纬仪LT202L不仅可作为电子经纬仪使用，还能在工程施工中提供可见的激光束，辅助施工人员进行精准定位。望远镜可绕过支架作盘左盘右测量，保持电子经纬仪的测角精度。同时，它还可以向天顶方向垂直发射激光束，作为激光垂准仪使用；若配置弯管读数目镜，则可根据竖盘读数对垂直角进行测量；当望远镜照准轴精细调成水平后，又可作为激光水准仪及激光扫平仪使用。
English Introduction
The SuGuang Electronic Theodolite LT202L is a dual-laser electronic theodolite launched by Suzhou Yiguang. It is equipped with a laser emission system in addition to the traditional electronic theodolite functions, making it capable of meeting measurement requirements in various scenarios.
The electronic theodolite part of this instrument uses a grating incremental digital angle measurement system and is combined with microcomputer technology to achieve functions such as measurement, calculation, display, and storage. Its angle measurement accuracy reaches 2″, with a minimum reading of 1″, which can meet the requirements for high-precision angle coordinate measurement and directional alignment measurement.
The telescope has an objective aperture of 40mm or 45mm, a magnification of 30 times, a field of view of 1°20′ or 1°30′, a shortest viewing distance of 1.3m or 2m, a stadia constant of 100, and a stadia additive constant of 0.
The laser emission system uses a 635nm semiconductor laser emitter. The laser is coaxial and confocal with the telescope s sighting axis. The effective range of the laser is up to 200m in daylight, with a spot size of 5mm/100m and a deviation of no more than 5″ between the spot center of the focused laser beam and the telescope s sighting axis.
In addition, the instrument is also equipped with a dual-sided display, reticle, lighting system, etc., which facilitates users in operating under different environmental conditions.
The SuGuang Electronic Theodolite LT202L can not only be used as an electronic theodolite but also provides a visible laser beam in engineering construction to assist construction personnel in precise positioning. The telescope can rotate around the bracket for left and right measurements, maintaining the angle measurement accuracy of the electronic theodolite. At the same time, it can also emit a laser beam vertically towards the zenith to be used as a laser plummet. If equipped with a bent-tube reading eyepiece, it can measure vertical angles based on the vertical circle reading. When the telescope s sighting axis is finely adjusted to be horizontal, it can also be used as a laser level and laser plane instrument.
