核心技術(shù)特點
儀器采用一體化激光器設(shè)計，激光功率可調(diào)節(jié)以適應(yīng)不同環(huán)境光線，通過望遠鏡目鏡可直接觀測清晰激光光斑。電子補償器可自動修正垂直軸傾斜誤差（補償范圍±3′），配合30倍正像望遠鏡（視場角1°30′）和1米最短視距，確保近距離測量的精準性。LT402L型號獨有的上激光指向功能，可在船舶制造、橋梁工程等場景中實現(xiàn)目視觀察與激光指向同步作業(yè)。儀器標配6V鎳氫電池，續(xù)航達15小時，工作溫度范圍-20℃至+50℃，適應(yīng)多種戶外環(huán)境。101121
應(yīng)用場景
該系列廣泛應(yīng)用于重大工程項目，包括：大型船舶制造中的機件變形監(jiān)測、水壩壩體位移測量、隧道與井巷工程的軸線校準、港口橋梁施工控制，以及飛機機架安裝等高端工業(yè)領(lǐng)域。在建筑領(lǐng)域，特別適用于超高層鋼結(jié)構(gòu)垂直度控制、幕墻安裝定位等需要高精度角度基準的作業(yè)。儀器153×175×328mm的緊湊機身和4kg重量（含電池）設(shè)計，兼顧了便攜性與穩(wěn)定性。31222
Introduction in English
The FOIF DT402L/LT402L Series Laser Electronic Theodolite, developed by Suzhou FOIF Co., Ltd., is a professional surveying instrument designed for high-precision angle measurement and alignment tasks. Featuring an absolute encoding system with 1″ minimum reading, the device incorporates a 635nm semiconductor laser emitter (effective range 200m in daylight) and dual-axis electronic compensator (±3′ range). The LT402L model s unique dual-laser system provides both upward and downward pointing capabilities, enabling vertical plumb line measurements for skyscrapers, tower installations, and other zenith-referenced applications. 61015
Technical Highlights
Equipped with a 30× magnification erect-image telescope (1°30′ field of view) and laser spot visible through the eyepiece, the instrument allows simultaneous optical observation and laser guidance. The modular design includes adjustable laser intensity, RS-232C data interface, and lightweight magnesium alloy construction (4kg). Standard configuration includes laser plummet (80m range, 0.5m minimum focus), while the LT402L adds upper laser pointing with ≤5″ alignment accuracy. Operable from -20℃ to +50℃ with 15-hour battery life, it meets demanding field conditions. 111317
Industrial Applications
Ideal for large-scale engineering projects such as shipbuilding deformation monitoring, dam displacement measurement, pipeline laying, and bridge construction control. Its precision proves critical in aerospace applications like aircraft frame assembly, as well as urban infrastructure projects including subway tunneling and high-rise steel structure verticality verification. The compact design (153×175×328mm) with shock-resistant casing ensures reliable performance in harsh environments. 92023
