Light probe FDP-7UVIR200-2-yy

gapopticalspectrometer

Transmission dip probes are used for online and inline absorbance measurements in fluids. When dipping or permanently mounting the probe end into the fluid, absorbance can be measured. A standard SMA-905 connector is used to couple light into a fibre bundle, typically consisting of six fibres (other configurations available upon request). The light is transmitted to the probe end, where it crosses the predetermined gap and is then reflected against a diffuse white reflective material back onto the receiving read fibre, which is coupled to a spectrometer on the second leg of the probe. The read fibre is placed in the center of the illumination fibre bundle to provide the best collection efficiency for the probe. Both bundles are housed in flexible stainless steel jacketing and the probe tip is also made of stainless steel. At the mid-point of the assembly a ferrule is used to split the fibres into their respective legs (illumination and read) which are terminated in SMA-905 connectors.
