Product Details
High power laser field mirror is used in high power laser welding, laser cutting and other fields of high precision scanning field mirror, its characteristics are: can withstand 3KW to 6KW high energy continuous laser, the full field of view to meet the requirements of the flat field, image quality to the line emission limit. The high-power F-theta field mirror reduces thermal offset from high-power, short-pulse lasers for higher damage thresholds. Huapeng Iwei high power quartz welding field mirror 1080nm-30 spot SiicaA is divided into two models, the other is a high power quartz welding field mirror 1080nm-30 spot SiicaA, is not with water cooling. Field mirrors can be divided into f-theta lenses and telecentric lenses. Due to the high cost and expense of telecentric induction mirrors, F-theta lenses are mainly used in laser welding machines for industrial applications. In the absence of deformation, the position of the focus depends on the focal length of the lens and the tangent line of the deflection Angle, and the position of the focus depends only on the focal length and deflection Angle, which simplifies the calculation method of focus positioning.
Selection of field mirror: the main technical parameters to consider are working wavelength, incident pupil, scanning range and focusing spot diameter.
Working wavelength: mainly to see the wavelength of the laser, the field mirror is coated at the given laser wavelength. If the mirror is not used within the given wavelength range, the field mirror will be burned out by the laser.
Incident pupil: If a single lens is used, the reflector is placed at the place of the incident pupil, and the diameter of the
maximum available light beam is equal to the diameter of the incident pupil.
Focused spot diameter: For a scanning system with incident laser east diameter D, field mirror focal length F and beam quality factor Q, focused spot diameter d=13.5QF/D(mm). Therefore, a smaller focus spot can be obtained by using an east enlargement mirror.
Scanning range: The larger the range that the field mirror can scan, the more popular it is with users. However, if the scanning range is increased, the focusing point is larger, and the distortion degree is also increased. In addition, increase the scanning range, field mirror focal length and working distance should also be increased. The lengthening of the working distance inevitably leads to the loss of laser energy. There is also the focused spot diameter is proportional to the focal length, which means that the increase of the scanning range, the focused spot diameter increases, the spot is not fine enough, and the power density of the laser decreases very fast (the power density is inversely proportional to the second square of the spot diameter), which is not conducive to processing. Therefore, the user should choose the most suitable field mirror according to the different processing area, or spare several field mirrors with different scanning ranges.
