Technical Field
[0001] This utility model relates to the field of imaging lens technology for DI lithography machines, and more particularly to an imaging lens for DI lithography machines with optical power detection function. Background Technology
[0002] A DI lithography machine is a processing device used in the PCB manufacturing industry. It requires an imaging lens, which is one of the core components of the lithography machine. This lens focuses a light beam onto the PCB, directly printing circuit patterns onto the board. Current DI lithography machine imaging lenses lack light intensity monitoring capabilities. When the light intensity from the light generation module to the light processing module is insufficient or excessive, it will affect the processing quality of the product. If this is not detected in time during mass production, it will result in a large number of defective products, causing significant losses. Summary of the Invention
