SEI laser G8 Nd:YAG DPSS

G8 is a state of the art engraving & marking laser system dedicated to metallic and thermoplastic materials, G8 is completely designed and manufactured by the leading Italian laser company SEI S.p.a. All G8 components; laser source, optics, mechanics, electronics and software have been designed by SEI to achieve the highest performances available on the market for this range of products today.

■ The G8 features a full width front opening cover providing excellent access to the 450x450 mm working area enabling quick/easy loading & unloading operations. Additional access is also provided by two hinged side panels for even greater accessabilty for marking larger pieces/ components. The Z axis has an automatic 300 mm stroke programmable via the Icaro software. This feature enables the G8 to process a wide range of sizes and shapes, even fields greater than the work area can be processed. Another remarkable feature of the G8 system is represented by the presence of a “dynamic beam expander”, this enables the laser spot size to be driven dynamically adjusting the spot size of the laser via software, producing high quality engraving/marking even on items with different surfaces heights.

G8, the right solution for small craft companies up to larger industry/manufacturing companies.

■ The G8 is a Class 1 product and as such complies with the following strict (CE, CDRH, IEC 825-1).International standards.

■ Steady high enblock aluminum frame.

■ Hi-end engraving quality tank to the smaller spot size available <25 μm (f100).

■ Dynamic Beam expander (dynamically shifts the focus spot) for marking objects with uneven

surfaces. It optimizes positioning and marking times.

■ Up to 1.6 mJ pulse Energy peak and peak power 200 kW (20W).

■ Loading table 450x450 mm.

■ Inclusive Electronic Z axis - programmable via software - vertical stroke 300 mm.

■ Side doors can be opened to allow processing of non standard sized objects (only in Class 4).

■ Electronic TW rotation axis programmable via software (option).

■ Red diode laser pointer with marking path protection.
