Double-Pass Transmission Probes

The process-ready Double-Pass Transmission Probe is useful for online measurement of sample streams in demanding environments. The probes is available in various pathlengths and materials, have linearity superior to that of transflection probes, and can be used as part of a process system or combined with Ocean Optics spectrometers and accessories to create real-time monitoring systems for a variety of transmission applications.

The Double-pass Transmission Probe sends light energy from a source through the sample by folding the beam 180° back via a protected reflector. The amount of transmitted/absorbed light is measured by the detectors and read out locally; a re-transmitted 4-20 mA output proportional to concentration is supplied. Pathlengths from 2-10 mm are available. Probe length can be increased if automatic retractable devices are required. This is a custom option that requires consultation with an Applications Scientist.
