Immersion Transmission Probes

transmission immersion fibre optic probe

For online and inline absorbance measurements in fluids, immersion transmission dip probes can be used.

When dipping or permanently mounting the probe end into the fluid, absorbance can be measured. A standard SMA905 connector is used to couple light into a fibre bundle, which typically is a bundle consisting of six fibres (other configurations available upon request). The light is transmitted to the probe end, where it crosses a predetermined gap and is then reflected against a diffuse white reflective material (or mirror) back into the receiving read fibre, which is coupled to a spectrometer on the second leg of the probe.


The read fibre is placed in the centre 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 SMA905 connectors.

All our fibre optic probes can be customised to meet your specific requirements.

Other lengths and fibre types are available. Specify xx = UV for UV/VIS fibre cables, IR for VIS/NIR and UVIR for broadband UV/VIS/NIR
