Scientists from Leibniz University in Hanover have pioneered the development of a new manufacturing technology - UV LED based microscopy projection lithography. This technology is expected to completely change the manufacturing method of optical components, providing high resolution at lower cost and ease of use. The MPP system utilizes the power of UV LED light sources to transcribe the structura...
TRUMPF will launch a new generation of efficient fiber lasers at the Munich Light Expo in Germany, which can meet the diverse welding needs of the entire industry, such as high-precision welding of electric vehicle batteries. Tom Rentschler, Product Manager of TRUMPF Fiber Laser, said, "The new generation TruFiber laser is the core engine of our production solutions. Through deep collaboration wit...
Recently, scientists used laser gyroscopes to measure that the change in Earth's rotational speed is less than one millionth. This technology can help scientists understand the complex flow of water and air, which can cause the smallest adjustments to the Earth's rotation.The Earth's rotation is not completely stable. Planets accelerate or slow down as they rotate, slightly shortening or prolongin...
BEIJING, Dec. 19 (Xinhua) -- A team of Chinese researchers used a novel theory to invent a new type of ultrathin optical crystal with high energy efficiency, laying the foundation for next-generation laser technology.This photo taken on Dec. 15, 2023 shows a Twist Boron Nitride (TBN) crystal placed on a piece of fused silica in Peking University, Beijing, capital of China. A team of Chinese rese...
Summary:To filter out infrared light from the driving light source in the extreme ultraviolet lithography (EUVL) light source system, a rectangular grating structure needs to be fabricated on the surface of the collection mirror. However, the collection mirror grating usually undergoes deformation during the manufacturing process, resulting in a decrease in filtering efficiency. The process errors...
