MNL 300

MNL 300 nitrogen laser

The MNL 300 is the ideal light source for applications like fluorescence, phosphorescence and mass spectrometry in research, medical diagnostics and industry.

  • Wavelength 337,1 nm
  • Long operating life
  • For low-cost applications
  • Compact design
  • Certifications: CE, ETL-Report No. 2212292WIE-004 (Intertek: UL, CSA), ROHS, FDA
  • Compatible with VSL337i OEM

Setup

Compact, reliable and cost-efficient, the Mini Nitrogen Laser MNL 300 can provide pulse energies up to 85 µJ and repetition rates up to 80 Hz with a maximum average power of 5 mW. It is characterized by its long lifetime, low energy decay and high precision. This is achieved by the patented innovations:

  • Sealed cartridge in metal-ceramics technology
  • Directly switching solid state power switch

The MNL 300 presents the advantages of modern laser technology. Only an external trigger signal is required for its operation. That is the reason why its use is so simple. The standard version with free beam can be equipped with an optical fiber for the light output allowing the best integration into the customers‘ applications. Moreover it is possible to couple the MNL 300 with a tuning module in order to provide several wavelengths of the whole visible spectrum.

The air-cooled MNL 300 is supplied with a low voltage of 24 V DC / 60W. A wide range power supply (100 – 240 V, 50 – 60 Hz) can be obtained from LTB, if required. Small, compact, with a total volume of 2.2 litres, the MNL 300 will provide you the best performance of a UV-laser in this price segment.

Options:

  • Fiber coupling and fibers
  • Dye laser module
