Specifications:
The document outlines four laser models: LZR NANO, LZR ECO, LZR PRO, and LZR 3D. All models operate at a wavelength of 1064 nm and have a power supply of 110V or 230 VAC at 50/60 Hz. The output power varies across models, with LZR NANO and LZR ECO offering 20 W and 30 W, while LZR PRO and LZR 3D offer up to 200 W and 100 W respectively. The M2 value is less than 1.8 for NANO and ECO, less than 1.6 for PRO, and less than 1.6 for 3D, with a special case of less than 1.4 at 200 W for PRO.

Dimensions and Weight:
The dimensions and weight vary, with LZR NANO being the smallest and lightest at 65.2x39.2x62.9 cm and 35 kg, while LZR 3D is larger at 96.5x47x10.5 cm and weighs between 55 kg and 60 kg.

Performance:
The marking area and focal lengths differ, with the maximum marking area being 160x160 mm for LZR PRO. The speed of the salvo head ranges from 5000 mm/s to 7000 mm/s. Maximum pulse energy is up to 1 mJ for most models, except LZR 3D which offers up to 1.5 mJ. The maximum frequency reaches up to 1000 kHz.

Cooling and Laser Class:
All models use air cooling and are classified as Class IV lasers, with LZR 3D also having a Class 4/1 classification.

Applications:
These laser systems are suitable for engraving solutions on rings, bracelets, medallions, watches, and eyewear. They can also cut individual pieces manually or in a production line setting.

Key Features:
The systems include R- and Z-axis capabilities, enhanced laser chamber visibility, multiple cutting process tools, an optional scanner detection system, a double positioning pointer, a pulsed fiber laser, a touch screen interface, and a 36-month warranty.
