The market demand for filters drives the application of laser cutting machines

Infrared cut-off filter is a filter element for optical applications, whose function is to filter infrared light through visible light. This kind of filter is mainly widely used in mobile phones, cameras, vehicle equipment, tablet computers and security monitoring and other imaging camera core components. With the rapid development of the consumer electronics industry, the market demand for infrared cut-off filters has increased, and equipment processing manufacturers have also taken the wind. Filters have high requirements for processing equipment, and the green picosecond laser cutting machine can precisely meet the processing needs of infrared cut-off filters.

Green light wavelength of 532nm, visible light, can be filtered through the coating layer, the use of objective lens or wire, can be focused in the glass layer, destroy the internal stress of the glass, so as to achieve the purpose of cutting. In the processing of infrared cut-off filter, green picosecond laser cutting machine plays an important role. First of all, non-contact processing, because the laser processing only the laser beam and the workpiece contact, there is no cutting force for cutting parts, to avoid damage to the surface of the processed material. Secondly, the laser processing precision is high, and the thermal effect is small. The pulsed laser can achieve very high instantaneous power, very high energy density and very low average power, which can be processed instantaneously and the heat affected area is very small, ensuring high precision machining and small heat affected area. And the processing efficiency is high, the economic benefit is good. Laser processing efficiency is often several times the mechanical processing effect and no consumables pollution-free.

Picosecond laser cutting process has many advantages such as fast cutting speed, no dust generation, no cutting substrate loss, small cutting path required, and complete drying process. Depending on the position of the circular sample, the cutting head can be used to cut 4 straight lines around each circular sample for auxiliary segments. Focus into bessel beam, cut the filter with a certain point spacing, cracks can be formed between the points, and finally spread the film split to complete the cutting of the filter. The filter cut out by the green picosecond laser cutting machine is of high quality, effectively improving the yield of the cutting filter and improving the cutting efficiency. Laser cutting machine is currently the best cutting tool, with the increasing requirements for equipment in various industries, but also affected by various industries, the demand continues to rise.
