Gamma Radiation Threshold Levels

by Jerry Philips | 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 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...

Probes for Internal Thread Inspection

Dec 17, 2013 | Non-Contact Sensing, Quality Control, Thread Inspection

The Problem: Inspection of the integrity of small internal threads such as M10. The Solution: Very small fiberoptic probes can be made having two diametrically opposed sensors. The probe can be used to scan the length of internally threaded holes as the probe is...

Blue Light Sensors

Jul 17, 2013 | Hot Targets, Quartz Fibers

INTRODUCING Blue Light Sensors for displacement measurements on extremely hot targets. Metals emit light energy in the red spectrum when heated above 600°C. Red-glowing parts interfere with displacement measurements of optical sensors that use red lasers or LEDs as...
