Recently, three invention patents of XIOPM were authorized. They are a method and tool of dismantling glue of assembly parts of optical machines (Patent No. 200910254425.4), a collapsible lens hood of optical camera (Patent No. 200910022264.6) and a secondary mirror support structure of Cassegrain system camera (Patent No. 200910021691.2).
“A method and tool of dismantling glue of assembly parts of optical machines” solved the following technical matters existing in dismantling glue of assembly parts of optical machines: pollution of mirror film, size distortion, and structural damage. It has the physical advantages of simple operation and no effect on optical components.
“A collapsible lens hood of optical camera” solved the following technical matters existing in lens hood of optical camera: increased storage volume and weight gain because of the increased length of hood. It has the advantages of small size, light weight, rigidity, being deployable, wide applications and being cascadable.
“A secondary mirror support structure of Cassegrain system camera” overcame the defects of greater weight and adjustment difficulties in three supporting structure of existing secondary mirror support structure. It has the advantages of light weight and convenient adjustment.
