Turbine Speed Probes

by | February 10, 2023 | Fiberoptic Sensors, Non-Contact Sensing, turbine speed probes | 0 Comments

The previous App Note 'Bending Light' showed that the light beam emitted from a fiber optic probe can be redirected to a different emission angle by polishing the fibers at an angle to the probe axis. A new customer wants to measure turbine speed by sensing the...

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...

Sensor Overview

Feb 21, 2020 |

This short video highlights Standard and Customized Sensors. These devices are commonly inserted/installed into equipment or machinery that may present extreme conditions to the probes. Most applications require some customization of the probes and fiber optic cables....

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.
