Description
Transmission dip probes couple to Ocean Insight spectrometers and light sources to measure absorbance and transmission in solutions. These stainless steel probes are great for embedding into process streams for real-time sample monitoring.
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 onto the read fiber within the probe ferrule.
Probe options — versions for general lab use and harsh environments
Sampling — sample is free to flow through the probe tip
Pathlength — vary the pathlength of your probe tip (2 mm, 5 mm or 10 mm) for solutions of different concentrations
Simple mounting — probe fits into a standard 1/4″ Swagelok fitting for installation into a pipe or reactor
