J2-JC Laser Optical Theodolite
Product Introduction
J2-JC Laser Optical Theodolite is a high-precision surveying instrument that integrates optical angle measurement technology with laser pointing technology. By utilizing the strong directivity and concentrated energy characteristics of laser beams, this instrument provides accurate, efficient, and convenient solutions for alignment, positioning, angle measurement, and deformation monitoring applications.
The J2-JC laser theodolite is widely used in large-scale shipbuilding, heavy machine tool calibration, aircraft frame installation, port and bridge engineering, dam displacement monitoring, pipeline construction, tunnel engineering, high-rise buildings, tower structures, vertical alignment measurement, and leveling applications.
Featuring a short-distance telescope design, digital angle reading, coaxial laser pointing, and automatic vertical circle indexing, the J2-JC provides reliable performance for various special surveying tasks requiring high accuracy and operational efficiency.

Key Features
• High-Precision Laser Alignment
Equipped with a laser diode system, the instrument provides a highly directional laser beam for precise positioning and alignment measurements.
• Coaxial Laser Pointing System
The laser beam is coaxial with the telescope optical axis, ensuring accurate target positioning and reducing measurement errors.
• Clear and Bright Telescope View
The telescope delivers a bright and clear field of view, enabling convenient observation under different working conditions.
• Digital Angle Reading
The digital display provides fast, reliable, and accurate angle readings, improving measurement efficiency.
• Automatic Vertical Circle Indexing
The vertical circle index automatically returns to zero, making vertical angle measurements faster and more precise.
• Compact Design for Special Surveying Applications
The short-distance telescope design makes the instrument suitable for specialized measurement tasks in confined or complex environments.

Working Principle
The J2-JC Laser Optical Theodolite combines traditional optical theodolite technology with laser projection technology.
During operation, the telescope is used for optical target observation, while the built-in laser diode generates a visible laser beam along the telescope axis. The operator can accurately determine alignment positions and measure horizontal and vertical angles through the digital angle reading system.
The laser beam provides precise reference points over long distances, while the high-resolution angle measurement system ensures accurate surveying results for engineering construction and deformation monitoring.
