Transmission dip probes are designed for on-line and inline absorbance measurements in fluids. By dipping or permanently mounting the probe end into the fluid, absorbance can be measured. Explore our range of transmission dip probes below.

Transmission Probes

Transmission dip probes are used for on-line and inline absorbance measurements in fluids. By dipping or permanently mounting the probe end into the fluid, absorbance can be measured. A standard SMA-905 connector couples light into a fiber bundle, typically consisting of six fibers (other configurations available upon request). The light is transmitted to the probe end, where it crosses a predetermined gap and is reflected against a diffuse white reflective material back onto the receiving read fiber, which is coupled to a spectrometer on the second leg of the probe. The read fiber is centrally placed within the illumination fiber bundle to provide optimal collection efficiency. 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 splits the fibers into their respective legs (illumination and read), which are terminated in SMA-905 connectors.

Mini Transmission Probes

For absorption measurements in miniaturized centrifuge tubes or vessels, Avantes offers the mini transmission dip probe. It features a miniaturized tip that is 130mm long and 3.2mm in diameter. The mini transmission dip probe has a fixed optical path length of 5 or 10 mm. It is available in three versions: one for UV/VIS (200-800 nm) measurements, one for VIS/NIR (350-2500 nm), and one for UV/VIS/NIR (250-2500 nm). For best results below 240 nm, solarization-resistant fiber (-SR) is recommended. The probe features Avantes ME, chrome-plated brass, and jacketing. Optionally, the probe can be configured with a longer stainless steel or Hastelloy® tip or other jacketing options (MS, BX, or PVC). It has two SMA connectors (FC/PC also available) for convenient coupling to the Avantes line of spectrometers and light sources.

Mini Transmission Dip Probes with Variable Path Length

This fiber-optic probe features a variable and adjustable path length for more flexibility during absorbance measurements in fluids. The gap between the fiber and the diffuser can be set anywhere between 0.25 and 10 mm. A standard SMA-905 connector couples light into a fiber bundle, typically consisting of six fibers (other configurations available upon request). The light is transmitted to the probe end, where it crosses the predetermined gap and is reflected against a diffuse white reflective material back onto the receiving read fiber, which is coupled to a spectrometer on the second leg of the probe. The read fiber is centrally placed within the illumination fiber bundle to provide optimal collection efficiency. 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 splits the fibers into their respective legs (illumination and read), which are terminated in SMA-905 connectors.
