[INQ. NO. 2407E18] Photo Litho G Co., Ltd. has been specializing in optical process and optical system technology optimized for the field for 30 years, and has particularly specialized in developing, delivering, and post-support optical systems and LED light sources, which are key processes in the Lithography process that require fine pattern production such as LCD, OLED, PCB, and touch panel.
The LED light source and optical system for the exposure machine are the key units that enter the exposure equipment, which is the main equipment of the photo process, during the Lithography process that requires the production of fine patterns such as LCD, OLED, PCB, and touch panel. The lamp of the existing exposure machine used ultra-super high-pressure Mercury Short Arc Lamp, which was changed to the LED light-source method and applied the optical system accordingly.

The LED light source and optical system for the exposure of Photo Litho G have solved many problems with the existing ultra-high-pressure mercury lamp method and guarantee many advantages to customers who apply it.
Firstly, various cooling systems caused by heat generated by the existing ultra-high-pressure mercury lamp method were omitted, and various optical components for condensing and transmitting light were eliminated, enabling a simple system, and thus resulting in the significantly reduced equipment manufacturing and maintenance costs.

The improved life expectancy led to reduced costs in production and replacement
Secondly, the expected useful life was improved dozens of times compared to conventional lamps, thereby dramatically reducing production losses and lamp replacement costs caused by equipment stops when replacing lamps.

Thirdly, by applying monochromatic light, the resolution, which is one of the most important performances for the formation of fine patterns, has been improved. Additionally, various problems caused by the absorption of light of various wavelengths on the exposed object during exposure have also been significantly improved.
Finally, it is harmless to the human body because there is no ozone generation by UV of 185nm wavelength, and there is no risk of explosion due to poor cooling of existing lamps. In addition, it is an eco-friendly product that does not contain toxic substances (mercury, etc.) generated when disposing of existing mercury lamps, and it meets global environmental requirements.
“In line with the rapidly changing production processes, we want to continue to support optimal LED light sources, optical systems and applications with reasonable prices and optimal efficiency products to become a company that grows together with customers,” remarked the company’s CEO.
