As luxury a problem as having too much signal can be considered to be, it often can be troublesome and its necessary to reduce the strength. For all UV/VIS/NIR applications where light intensity needs reducing, our inline fibre optic attenuator is a great solution.
This device is an iris attenuator which controls light throughput to avoid detector saturation. Its connects inbetween two SMA terminated fibre optic cables and the light source and consists of two UV/VIS/NIR collimating lenses mounted on either side of the iris. The attenuation can be set from 0-100% and can be fixed with a set screw.
An budget brass version without collimating lenses is also available which utilises an adjustable pin to simply disturb the beam and therefore reduce throughput. Whilst certainly not as elegant as the iris, it is very effective and an excellent choice.
