Selection Considerations

Aperture Size
The various aperture sizes available permit selection of spatial resolution and noise performance. Smaller aperture sizes provide finer spatial resolution. Larger aperture sizes provide lower noise.

End View/Side View
Trek probes are available with end-viewing or side-viewing detectors to accommodate the constraints of an installation.

Round and Square Bodied Probes
Selected Trek probes are available in round-body and square-body styles to accommodate different mounting requirements.

High Temperature
Probes are available with enhanced operating ranges for high temperature applications.

High Resolution
Probes are available with high resolution for critical measurements.

Transparent Probes
Transparent probes are used in applications where light must pass through the probe, such as photoconductor testing. This allows illumination and measurement of the same spot on the surface. The housing and sensitive electrode of the probe are made of a special optically transparent, electrically-conductive glass.

Special Purpose Probes
Trek application engineers can help solve many problems with custom designs and innovative solutions. Please contact TREK, INC. for more information.
