Laser Direct Imaging (LDI)

Maskless lithography can be realized by LDI. It has many advantages in imaging resolution, alignment accuracy, product yield, automation and so on. Which is rapidly replacing traditional mask exposure production methods. 3D printing of materials such as polymer, ceramics can also be realized by LDI.

Han’s TCS can supply 405nm semiconductor laser system to manufacturers of LDI devices. Based on high quality chips, we can ensure the stability and uniformity of exposure energy, advanced technology, excellent performance. We have many LDI equipment customers and rich industry application experience.

As a leading semiconductor laser diode and system manufacturer in China, Han’s TCS  has reached the international leading level in semiconductor laser diode packaging and fiber coupling technology. We provide 405nm laser system with 12W, 24W, 30W, 50W, 100W multiple power levels for the LDI industry.
