The Mini Nitrogen Laser MNL 100 is characterized by its long service life, low energy loss and high precision. This is achieved through the patented innovations

closed laser tube in metal-ceramic technology and
direct switching semiconductor power switch.

60 million laser pulses or maintenance-free operation for 2 years are guaranteed. An integrated laser controller enables extensive presettings and easy adaptation to different applications. The firmware allows the laser functions and parameters to be set and controlled via a PC interface. All trigger inputs and outputs are monitored by the trigger management system. The laser is supplied with an extra-low voltage of 24 V DC and is air-cooled. The scope of delivery includes a wide-range power supply unit (90 – 260 V, 50 – 60 Hz).

The MNL 100 is largely compatible with lasers of this class on the market and has the necessary certifications for all international markets: CE, ETL Report No. 05KFI005386 (UL, CSA, VDE, Semco), ROHS, FDA. Adaptation kits for installation in MALDI-TOF mass spectrometers or LIF systems from various manufacturers are available from LTB on request.
