Generally, the scan prism typically all optical glass in existing three-dimensional laser scanner does substrate.
Concrete, scan prism is connected with bearing, to realize the high speed rotating of scan prism；Scanning is being installed
When prism and bearing, need insert a bearing into the endoporus of scan prism and fix.In reality, scanning
It is tight fit in design that the hole axle of prism and bearing coordinates, and the interior hole machined of glass scan prism is smart
Spending the most undesirable, deviation is big, and this makes the assembly difficulty causing later stage scan prism and bearing very big,
During as bearing interleave scan prism endoporus do not reaches the installation site of requirement the most stuck).Glass
It is damaged that the prism of substrate the most easily collapses limit when stress is excessive.
Inventor finds under study for action, the non-optical glass substrate of three-dimensional laser scanner in prior art,
Processing characteristics and precision are poor, easily occur collapsing the problem that limit is damaged in processing and assembly project, and
And scanning mirror is the element of high speed rotating, impaired glass elements all carries to the performance of complete machine and safety
Come uncertain.
