Fibre coupled white light source

WLS100 from Bentham

The WLS100 is a turn-key, fibre coupled white light source, designed to maximise the coupling of broadband light into terminated fibre optics (FC, SMA, etc). A 100 W quartz halogen (QTH) lamp features exceptional output stability and of distance from electrical connections to filament therefore obviating the need for alignment on changing the bulb. Research-grade input optics ensure an efficient coupling into the fibre to further maximise power output. A condenser lens assembly ensures optimal coupling to the optical fibre of choice. The front panel may be fitted with either an SMA or FC connector.

  • Alignment free lamp replacement
  • Fitted with a switch mode power supply allowing use with mains supplies 85 V AC - 265 V AC
  • A 2.5 A slow blow fuse is fitted
  • Bentham Part 09101 for optimal filament position with respect to the output optics
