Sapphire Window Optical Probe for Polymer Melts from Celsum Technologies - Instrumentation for rheology, strain gages, pressure transducers, load cells, temperature control, sapphire window optical probes, precision extrusion dies, and much more.

Our robust, straight-pattern, sapphire window optical probe is especially designed for use with various optical analysis techniques on processing and test machinery for polymers, pharmaceuticals, foods, and other materials. They may be used for research and development and process control.

Additionally, as well as transmission probes, we can offer you a variety of probes with diffuse reflectance optics, and test cells for liquids and gases.

We can supply adaptors to allow these probes (and others!) to be fitted to your equipment: let us have a sketch of your requirements and we'll send you a price. We can also supply high-temperature, armoured fibre-optic cables to connect our probes to your instruments.

Key features include:

Fitted with a sealed, abrasion resistant sapphire window in the probe tip
Maximum pressure 700 bars (10,000 psi)
Maximum temperature 420°C
600 micron, ultra-low-OH silica fibre with a 0.22 NA
SMA 905 compatible connector (others available)
