LDM-XT laser diode modules from LASOS are available in a free beam version or with a permanently aligned coupling into a single mode polarization maintaining fibre. The fibre patchcord can be designed by the customer choosing from various options regarding jacket and connectors. Additionally, the customer can choose from a range of opto-mechanical components like precision fibre plugs and sockets for adjustment free docking to an instrument or beam combining to transfer several beams into one collinear beam ore one fibre. Based on these features the new LASOS LDM-XT series is the best choice for

  • Microscopy
  • Flow Cytometry
  • Bioanalytical Research
  • Industrial Measurement
  • Testing
  • Science and Education

Product options include both free-beam and single mode fiber beam delivery, direct modulation to 300 MHz and wavelengths from 375 to 830 nm at power levels up to 250 mW. Options include enhanced beam circularity (C), Spectral Width of <1 nm (N), enhanced M2 value (E) or speckle homogenization, SHINE (H). The LASOS CommanderTM software offers PC based controls via USB interface.
