Security detector arrays are designed for the security market where X-ray energies range from 80 KeV to 9 MeV.

High Dynamic Range

Varex detection systems allow imaging the finest details in air (approx. 0.5 mm wire) while still being able to penetrate and see dense objects behind large amounts of steel.

Excellent Sensitivity

The detection system maintains incremental sensitivity to attenuation differences throughout a wide range

Small Element Size

The physical size of detector elements is another important determinant that contributes to spatial resolution.

Signal-to-Noise Performance

The detection system processes the input signal at various stages‚ starting from conversion of input X-ray photons into light‚ conversion of light into electrical signals, and finally conversion of electrical signal strength into digital form.

Scatter Rejection

Several special design and construction considerations are implemented in Varex detectors to minimize the effects of scatter.

Artifact Reduction

Varex’s detectors provide synchronized pulse control, reference output corrections, software imaging processing, adaptive signal thresholds, and other techniques to reduce and remove artifacts from the final images.


Penetration is a strong function of the X-ray source. Varex systems provide energies above about 2.5 MeV to achieve full penetration of a cargo container.
