Gamma Radiation Threshold Levels

by | September 12, 2025 | Gamma Radiation, Uncategorized | 0 Comments

Threshold dose Levels in Borosilicate Glass Fibers <50 rad (very low dose) No detectable changes in structure, optics, or mechanics. Any induced defects are below detection limits of spectroscopy. 10² – 10³ rad (100–1,000 rad) Beginning of trace radiation-induced...

Low Dosage Gamma Radiation

by | September 12, 2025 | Uncategorized | 0 Comments

Gamma radiation can interact with borosilicate glass fibers primarily by producing ionization and electronic defects in the glass network. At very low doses (<50 rad, or <0.5 Gy), the effects are generally minimal, but a few points are worth noting: Optical...

Vibration Proof Connectors

Feb 19, 2020 |

For applications where probes and fiber cables are exposed to high vibration levels, we recommend use of a wrench tight connector to make the connection vibration proof.    

CONNECTORIZED SENSORS

Feb 10, 2020 | , ,

Where it is desirable to be able to separate the sensor electronics from the measuring probes, fiber optic cables can be connectorized using a simple knurled finger tight design. And damaged tips can easily be replaced. TRANSMIT AND RECEIVE FIBERS ARE SEPARATED AT THE...
