Used LAM RESEARCH 490 #293655342 for sale

LAM RESEARCH 490 ultraviolet laser etcher / asher is a high precision manufacturing tool used to etch various materials at nanometer scale. It is a popular choice among industry professionals due to its high reliability and precision. 490 is designed to process a variety of samples, including metals, ceramics, and semiconductors, and is often used in microfabrication applications. LAM RESEARCH 490 utilizes a two-stage laser assembly. The first stage is a laser emitter which utilizes an excimer laser to assist with chemical etching and material transfer. It is capable of emitting 308 nm UV light with an oscillation frequency of approximately 25Hz and a pulse width of 7.5-12.50 ms. The second stage is a scanning equipment that acts to scan the surface of the sample using an X-Y galvanometer mirror. This allows the laser beam to be accurately and precisely positioned for targeted etching or surface treatment. The LAM 490 can be run in three different etching modes - Constant Current, Variable Current, or Spectral Selective. Constant Current mode is the most often used mode and sends a consistent laser pulse to the workpiece. Variable Current mode allows for the etching of deeper or wider features by varying the pulse width. With Spectral Selective mode, only certain wavelength wavelengths can be etched, which allows for more selectivity and control over the etching process. LAM RESEARCH 490 is also supplied with an automated system that allows users to monitor and control the etching process. This includes an array of sensors and associated software that allow users to track the current and voltage levels, sample temperature, and laser power. This unit ensures that the LAM 490 remains precise and stable on any given project. LAM RESEARCH 490 is also fairly small, weighing approximately 22 kg. This portability, combined with its precision controls, powerful laser capabilities, and included automation machine make 490 one of the most popular laser etching / asher units on the market. It is perfect for any application requiring high precision laser etching.
