Applications Notes
See how Philtec fiber optic sensors solve measurement challenges in aerospace, energy, cryogenics, medical technology, vacuum systems, high-pressure environments, and advanced research applications.
29_Reflection Interference
Guidance on avoiding reflection interference when mounting fiber optic probe tips near sidewalls or adjacent probes. Covers numerical aperture, beam angle by fiber type, target spot size, and minimum spacing calculations for Philtec sensor models.
V6N1_Measurements To Glass
A manufacturer of medical equipment needed to automate a manual process of aligning their glass encoder disc to a drive motor hub.
37_Gamma Radiation Effects
Documents degradation of standard glass fibers under gamma radiation exposure with cumulative dose charts. Introduces radiation resistant synthetic fused silica fibers rated to 10^8 rad and connectorized system designs to minimize RadHard fiber cost.
V6N31_Transparent Parts Measurements
To measure the distance to or shape of transparent targets using non-contact fi beroptic sensors.
65 Glass Thickness
With light based sensors, light rays will reflect off the front and the back surfaces of clear glass. The thickness of clear glass can be measured by using two sensors, with one mounted on each side of the glass.
V6N30_NeedleBrg
Philtec’s model RC100 fi beroptic probe with a 100 mil diameter fi ber optic probe proved to be the perfect fi t for this application. The probe is small, operation simple and the data very reliable. A mini-DMS unit with a TTL output comprises the automated inspection package
48_HDD
A customer inquired whether or not we could detect the axial runout (wobble) of a hard disc drive to establish a pass/fail criteria at ±20 μm pk-pk.
