Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithography machine technology, specifically to a compound eye structure for a lithography machine. Background Technology
[0002] A lithography machine compound eye refers to a system composed of multiple small lithography machine units, similar to the structure of a compound eye. This system improves the overall processing efficiency and precision through the coordinated work of multiple small lithography machines.

[0004] However, the existing compound eye structure used in lithography machines is inconvenient for adjusting the light source angle and the spacing between optical components, resulting in low optical efficiency in a four-inch optical system. Therefore, it does not meet the current requirements. To address this, we propose a compound eye structure for lithography machines. Utility Model Content
