Designed for our customers who require a less common wavelength for specialist applications, the I4 (1342) inherits all the excellent parameters of the I4 (1064).  Single longitudinal mode operation is available at modest power levels with 1 Watt output TEMoo at the top of the range.

  • Compact module utilising surface mount technology
  • Manual safety shutter
  • Fixed output power
  • Integral heatsink or heat spreader plate
  • User interface (interlock, on/off keyswitch etc.)
  • RS232 controllable
  • Active current limit
  • Current feedback mode
  • Auto power up sequence: warmup, current mode
  • Laser diode protection circuitry
  • Monitor following parameters:
    • Diode current limit, diode current setpoint, actual diode current
    • Diode & chipset temperature setpoint, actual temperature
  • Diode on-time LCD hour counter
  • Heatsink overtemp sensor > 50°C
  • Laser-head overtemp sensor > 39°C
  • Status & Diagnostic LED cluster
  • Designed and manufactured in the U.K.
