The term &#039;f-theta&#039; refers to the relationship between the focal length (f) and the angle (theta) of the laser beam as it scans across a flat plane. Unlike regular lenses that create a linear increase in distance with the angle, f-theta lenses produce a linear increase in distance for each unit of angle over a flat field. <br> <br>The primary function of an f-theta scan lens is to ensure a consistent spot size and marking quality across the entire marking field. This is crucial in applications where precision and uniformity of laser marking or engraving are essential. <br> <br>F-theta scan lenses are commonly used in laser systems for tasks such as marking barcodes, serial numbers, patterns, or intricate designs on materials like metals, plastics, and ceramics. The flat field of focus provided by these lenses allows for accurate and distortion-free laser marking over a specified area.&quot; <br> <br>As one of galvanometer manufacturers, we will do our best to meet all the needs of customers.

The laser input is integrated with a high power protection mirror to prevent dust and moisture, and prevent the risk of damage to the high power mirror. <br> <br>What Are The Differences Between 3-Axis <br> <br>The 3d dynamic scanning focusing technology is the core part of the galvanometer scanning laser marking control system. A dynamic focusing mirror is added in front of the common focusing lens, and the front and back positions of the dynamic focusing mirror are changed with the different scanning positions. The focus compensation is realized by fine-tuning the distance between the dynamic focusing mirror and the focusing mirror. The spot diameter of the laser beam far away from the origin is the same as that of the origin again to ensure the accuracy of focusing on the scanning plane, and then focus on the workpiece to be marked after scanning by X and Y galvanometer. By using X, Y galvanometers and Z lens to form three-dimensional focusing technology, the problem that the focal spot on the marking plane becomes larger and the marking line width is different is solved because the focal plane of the laser beam passing through the focusing mirror is spherical while the workpiece surface is planar. <br> <br>Hansscanner independently develops and produces a series of laser scanning heads (7mm, 10mm, 14mm, 20mm, 30mm, 50mm), voice coil motor and galvanometer system based on motion control technology, including 3D large area dynamic focusing system, high power galvanometer welding system, 5-axes drilling galvanometer, 4-axes platform linkage galvanometer, polygon scanning galvanometer, medical aesthetic fractional galvanometer, and weld tracking detection system.

Select the corresponding optical components according to the different laser wavelengths. Related options also include laser beam expanders, lasers, etc. The scanning galvanometer is an excellent vector scanning device. It is a special kind of oscillating motor, the basic principle is electrified coil in the magnetic field to produce torque, but with a rotary motor, the rotor with by using the method of mechanical new spring or electronic reset torque, size is proportional to the rotor Angle of deviating from the equilibrium position, when the coil and rotor deflection occurred at a certain current to a certain Angle. The electromagnetic torque is the same as the recovery torque. Therefore, it can not rotate like ordinary motor, can only deflect, and ammeter deflection Angle is proportional to the current, so the galvo head scanner laser is also called GALV scanning galvanometer. <br> <br>Working Principle of Laser Galvo <br>A galvo laser system from Hans Scanner is a high-precision tool that uses mirrors to rapidly steer a laser beam. Here&#039;s the core principle: <br> <br>Electromagnetic Dance: The Laser Galvo system relies on a special type of motor called a galvanometer scanner. This motor uses electromagnetic coils and a permanent magnet. When an electric current flows through the coils, it generates a magnetic field that interacts with the permanent magnet, causing the scanner to rotate. <br> <br>Mirrored Maneuvers: Mounted on the scanner are one or two tiny mirrors. By precisely controlling the current sent to the coils, the scanner rotates the mirrors, deflecting the laser beam in different directions. <br> <br>Digital Control, Agile Movements: Hans Scanner&#039;s Laser Galvo systems are typically digitally controlled. A computer sends control signals that determine the current sent to the scanner coils. This allows for highly precise and agile positioning of the laser beam. <br> <br>Why Choose Han&#039;s Scanner? <br>Han&#039;s Scanner originated from Han&#039;s Laser and grew in Han&#039;s Laser.
