Eastern develop and produce complete air cooling Fiber Optical Laser marking system in China. It is environmental friendly, low consumption, fully automatically and leading laser system. This creative laser system make the optical conversion rate up to 38%-50%, so only air cooling can meet the system requirements, this laser system is Small and compact size, Fiber output, can apply flexibly, and easy to make 3D processing system. Install backward reflecting isolator, which uses the particularity of wavelength and direction of laser, and the special structure inside the backward reflecting isolator, to block the laser reflected by work piece, in order to avoid the laser enter the laser oscillator again to damage the laser oscillator. Lens: F160 (Standard) F254 (Optional) Marking area: 110mmx110mm 160mmx160mm Power consumption: 200W Marking speed: <7000mm/s <7000mm/s Min. Character size: 0.3mm 0.5mm Min. Linear width: 50um 90um Output power: 20W Power stability (8h): <1%RMS Beam quality: <2 Pulse repetition frequency: <100KHz Marking graph: User-defined character, CAD data BMP, JPG, PNG, TIF, PCX, TAG, IOO, GIF, PLT Cooling mode: Air cooling Environmental temperature: 15C~30C Supply voltage: 220V/ 50Hz / 4A Overall consumption: <1.5kW Humidity: 45%~75% The fiber optic laser marker has advantage of high beam quality and high reliability. It is suitable for processing fields that need high marking depth, smoothness and accuracy. It is widely used in: Electronic components industry, medical device industry, glasses watch and clock industry, IC card industry, plastic tool industry, kitchen and bathroom appliance etc
