技术特点
J2-2光学经纬仪的核心优势在于±2″的一测回水平方向标准偏差，满足高精度角度测量需求。望远镜采用双胶合物镜与对称目镜结构，成像质量优异，最短视距2m，适应复杂环境。仪器配备20″/2mm长水准器和磁阻尼补偿器（补偿范围±3′），确保稳定性。三爪基座设计增强抗震性，净重仅6kg，兼顾便携性与耐用性。此外，读数显微镜支持水平与垂直度盘快速切换，测微器最小格值1′，数据读取直观高效。5617
应用场景
本产品广泛应用于大型建筑轴线定位、桥梁变形监测、矿山巷道贯通等工程领域，同时适用于天文观测辅助定位。其激光兼容特性（如搭配半导体激光器）可扩展至船舶制造、管道铺设等定向准直测量场景。夜间作业时，内置反光板照明分划板，保障全天候工作能力。31620
Product Overview
The FOIF J2-2 Optical Theodolite is a high-precision surveying instrument designed for triangulation, traverse measurement, and construction layout. Featuring an erect-image telescope with 30x magnification, it delivers bright and clear field of view, while the digital reading system ensures rapid data acquisition. The integrated wide-body support allows compatibility with Leica, Sokkia, and other infrared distance meters. Automatic vertical circle indexing simplifies elevation angle measurement, enhancing operational efficiency.1826
Technical Highlights
With ±2″ horizontal direction accuracy per measurement set, the J2-2 excels in angular measurement. Its optics combine cemented objective lenses and symmetrical eyepieces, achieving a 2m minimum focusing distance. The built-in magnetic-damped compensator (±3′ range) and 20″/2mm level vial guarantee stability. The three-claw base minimizes vibration interference, while the 6kg lightweight design ensures portability. Dual-axis reading microscopes (48x/62x) and 1′ micrometer resolution enable precise data interpretation.5627
Applications
Ideal for civil engineering (e.g., high-rise alignment), geological monitoring, and tunnel excavation, this theodolite also supports astronomical observations. The optional laser module (coaxial with telescope) facilitates shipbuilding and pipeline installation. Night operations are assisted by reticle illumination, ensuring uninterrupted performance.31621
