Transmission Dip Probes

Transferring a sample to a cuvette for an absorbance measurement isn’t always convenient, nor does it allow real-time monitoring of reactions and process streams. A transmission dip probe solves this problem by placing the “cuvette” at theTransmission of Solutions Measurements tip of a probe, with openings to allow solution to freely flow through during measurement.

How does it work?

In a transmission dip probe, light is transmitted from the illumination fiber through a plano-convex lens for collimation, after which it passes through the open probe tip to a flat, second-surface mirror at the tip of the probe. The light reflects from this mirror and is focused by the lens onto the read fiber within the probe ferrule. The advantage of the transmission probe is its compact optical design, which fits into a narrow stainless steel or PEEK body, or ferrule.

The trade-off with dip probes is that they measure both transmitted light and backscattered light from the sample, and have internal reflections that limit the dynamic range of the measurement. Still, they are a convenient and cost-effective option for many on-line and lab applications.
