Cuming-Lehman Chambers
Most antenna measurements need to be carried out in the far field; that is, the test antenna should be illuminated by a plane wave. Typically this is carried out by providing sufficient separation between the source and the AUT so the spherical wave approaches a plane-wave character.

EM-2107A | 30 MHz – 1.5 GHz -
Electro-Metrics Corp.
The EM-2107A is a standard test fixture for evaluation of the electromagnetic shielding effectiveness of planar material. The fixture is an enlarged section of coaxial transmission line and complies fully with the requirements of ASTM test method D4935-1. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred. The EM-2107A is provided with a reference standard test specimen, a dynamic range specimen. Dynamic range of greater than 80dB is achievable, although the cables and other test system components usually establishes the limiting factors.

EM-2108 | 1.5 GHz – 10 GHz -
Electro-Metrics Corp.
The EM-2108 is a standard test fixture for evaluation of the electromagnetic shielding effectiveness (SE) of planar materials. The fixture is a section of coaxial transmission line broken to allow the insertion of planar test materials. Although ASTM D4935-10 is currently limited to an upper frequency of 1.5 GHz, the EM-2108 meets and complies fully with both the impedance and SE requirements called out in ASTM test method D4935-10 up to 10 GHz. These results are shown in Figures 1 & 2. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred.

Arrow Tech
Provides real-time remote radiological monitoring. Local readout of hand-held meter allows for use as a portable survey instrument. More importantly, since the probe’s sensitive electronics are located far from the high field (25 to 350 feet away), they are not subject to destructive gamma exposure. The probe head may be placed directly into a filter compartment or against a resin tank or waste liner.

Infrared Laboratories, Inc.
The detector comes with an IR light collecting cone assembly, vacuum-sealed wedged window, field of view baffling, and low noise electronics. The bolometer system is then outfitted with a single cut-on IR filter or a cold, manually operated, 2 or 3 position filter wheel. We offer a selection of far IR cut-on long pass filters that range from 10 to 285µm.
