Philtec Fiber Optic sensors can make displacement measurements inside of mechanisms, machinery and vacuum chambers. To gain access to the measurement locations, Fiber Optic cables may be connectorized for the probe tips to be separated from the electronics. In some...

Turbine Speed Probes

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

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 Jerry Philips | 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...
