1064nm Ar Coating Jgs1 Laser Focus Lens For Laser Cutting Machine Parts
1.Scaning range
The area lens can scan,the more popular it will be with users.However,if we blindly increase the scanning area,it will bring a lot of problems.Such as points of light thicker,distorlion and so on.
2.Focal length
A.The scanning range is proportional to the focal length of the field lens-the increase of the scanning range will inevitably lead to the loss of laser energy.
B.The focal spot diameter is roporlional to the focal length.This means that when the scanning area reaches a certain degree,the obtained lightspot diameter is very large,that is to say,the concerntration is not fine enough,and the power density of the laser decreases very fast.
The fuction and application of focusing lens
1.Inprove the ability of edge beam to hit the detector.
2.In the same main optical syatem,the aditional field mirror will reduce the area of the detector,If the same detector area is used,the field of view can be enlarged and the incident flux can be increased.
3.Homogenize the non-uniform illumination on the photosensitive surface of the detector.
It is mainly used in laser marking machine,stage light,scientific test and laser measuring instrument.
