MNL 100

MNL 100 nitrogen laser

The MNL 100 nitrogen laser from LTB is representing the cutting edge in small compact UV lasers. It does not need an external gas supply. With a total volume of less than 3 litres, it weigths approx. 3.5 kg.

  • Wavelength 337.1 nm
  • MNL 100High Power up to 225 µJ pulse energy
  • Extremely long operating life through a sealed discharge cartridge in metal-ceramic technology
  • High precision through a directly switching solid state power switch
  • Warranty 60 million pulses (Long Life Version: 120 million pulses)
  • Patented
  • Certifications: CE, ETL-Report No. 05KFI005386 (UL, CSA, VDE, Semco), ROHS, FDA
  • Compatible with VSL337i OEM, VSL-337-ND

Setup

The Mini Nitrogen Laser MNL 100 is characterized by its long lifetime, low energy decay and high precision. This is achieved by the patented innovations

  • sealed cartridge in metal-ceramic technology and
  • directly switching solid state power switch.

60 million laser pulses or the maintenance-free operation over 2 years are guaranteed. An extension of the warranty up to 3 years is possible at an extra charge. The integrated laser controller makes a large number of presettings possible as well as the easy adaptation t o different applications. The firmware provides the possibility to adjust and control all laser functions and parameters via the interface to the PC. All trigger in- and outputs are monitored by the trigger management. The air-cooled laser is supplied with a low voltage of 24 V DC. A wide-range power supply is part of the delivery (100 – 240 V, 50 – 60 Hz).

The MNL 100 is largely compatible to the lasers of this class on the market and has got the certifications necessary for all international markets. CE, ETL Report No. 05KFI005386 (UL, CSA, VDE, Semco), ROHS, FDA.
