Transmission Dip Probes allow for real time liquid absorbance and transmission measurement without needing to use a cuvette. The probe consists of fiber optic cables which attached to your illumination source and deliver light through a lens system to your sample. Next the light is bounced off a probe mirror located in the tip of the probe and returned back to your optical fiber for detection via spectrometer. Dip probes are a convenient and cost-effective option for many on-line and lab applications.
Large Spectral Range of 190nm-2200nm
Enhanced Stability Design includes an integrated mode stripper which enables the end-user to move the probe after a reference has been taken.
Variable Pathlength Design enables the end-user to adjust the optical pathlength of the measurement (2, 5, 10, and 20 mm pathlengths are available).
The Dip Probe Tip fixes the light path for consistent absorbance / transmission measurements, and is easily changed to shorter or longer path tips to measure lower or higher concentrations.
Typical applications include color measurements, chemical concentrations, process monitoring, and environmental chemistry.
Standard Options
DP400-VISNIR is a dip probe with 400um fiber, 10mm path length tip, integrated mode scrambler to improve measurement repeatability for 400-2500nm.
DP400-UVVIS-SR is a dip probe for UV applications with 400um fiber, 10mm path length tip, integrated mode scrambler to improve measurement repeatability for 190-1100nm.
DP-TIP are replaceable dip probe tips for DP400 dip probe. Specify 2, 5, 10, or 20mm path. The Dip Probe Tip fixes the light path for consistent absorbance / transmission measurements, and is easily changed to shorter or longer path tips to measure lower or higher concentrations.
