The laser caliper is primarily composed of components such as a laser generator, optical system, detector, and signal processor. During measurement, a laser beam is emitted by the emitter and converges into a beam of light through the optical system. This beam scans the surface of the target, and the reflected light is received by the detector and converted into an electrical signal. The signal processor processes these electrical signals and calculates the diameter or radius of the target. 

The F-theta lens is a crucial component of the laser caliper, enabling the laser beam to maintain a stable focus during the scanning process. This makes it highly suitable for use as a scanning lens in laser measurement systems. Unlike regular lenses, the F-theta lens possesses a non-linear focal length, ensuring a consistent focus of the scanned laser beam within the plane. This characteristic is essential for achieving precise measurements.

During the measurement process, the F-theta lens focuses the scanned laser beam onto the surface of the object being measured, thereby capturing the reflected light signal from the object's surface. These reflected light signals are received by a photodetector, allowing for the accurate distance data of the object's surface to be obtained. The quality and performance of the F-theta lens directly impact the precision and stability of the entire laser measurement system. Our company offers customizable laser scanning F-theta lenses designed for various systems.
