CO2 Laser Coder LM Series

A robust, versatile, high-performance laser for industrial coding requirements, the new lM series from Hitachi is a carbon dioxide CO2 based vector laser. A wide range of wave-lengths as well as the flexible power and focal lens configuration ensures performance ideally suited to coding on various packaging substrates including paper, cardboard, glass or plastics. An innovative cascading cover design supported by an efficient cooling air stream provides a high level of reliability.

The result is very low electrical energy consumption and precise, clear coding even at small font sizes. Small outer dimensions and a powerful on-board control system enables easy hardware and software integration of the lM series into factory networks.



  • Compact single body space saving design for ease of mechanical integration
  • An electrical power consumption of 300 VA reduces the overall operating costs to a minimum
  • Dual casing structure provides for additional protection for the laser tube and optics which ensures durability against harsh environments
  • Most efficient air cooling by a cascading cover design extends laser tube lifetime
  • User-friendly interface PC based or with an optional colour 10.4” touchscreen
  • Highest print quality at a variety of production speeds using vector fonts with a user friendly font editing tool
  • Wavelengths of 9.3 μm, 10.2 μm and 10.6 μm combined with various lens options allows for coding onto a wide range of substrates

Easy Operation

The user friendly colour 10.4” touch panel is ready for immediate use. Our new, icon-based 10.4” full colour touch panel provides easy and straight-forward navigation. The WYSIWYG design provides stress-free operation by displaying marking data and settings immediately. The touch panel is easy to use in both handheld and equipment-mounted configurations.

Packaging Materials



Perfectly matched for the head absorption of plastics like polyethylene terephthalate (PET ), the 9.3 μm wavelength laser allows marking on plastic surfaces by smoothly melting the surface layer without creating pinholes or cracking the inner structure. This is the ideal solution for plastics being produced by polycondensated thermoplastic materials from the family of polyesters. Pet is widespread in the beverage industry and is mostly used for producing bottles.

Film and Foil

The 10.2 μm wavelength is ideally suited to marking on thin films and any type of packaging foil. Best results can be expected on painted films and foils with a thin ink layer on top. The laser energy removes the ink and generates a contrast to the next bottom layer, eg. to the metalised composite or aluminium. Packaging materials which absorb this wavelength very well and therefore generates best CO2 laser print quality are PE, HDPE, LDPE, PP, OPP, OPA, PA, PMMA, POM, PUR, ABS and PVC.

Paper, Cardboard and Glass

The CO2 laser radiation of 10.6 μm wavelength gets well absorbed in applications that process materials ranging from thin paper to cardboard type packaging. Extremely good print results are also achieved on any kind of glass products. This wavelength is the most common one available with CO2 lasers and perfectly suits the majority of packaging applications.
