Absorber
ETS-Lindgren has the ability to create customized absorber with special formulations and physical geometries to meet unique requirements. Workstations running advanced numerical modeling software are used to develop the right solution, which is then prototyped and tested to confirm predicted results.

EMC Absorbers
RF Microwave Absorbers

For decades, ETS-Lindgren has designed and manufactured some of the world's highest quality anechoic absorber material available for electromagnetic (EMC), radio frequency (RF), microwave and wireless test chambers and ranges. Now, with FlexSorb™ you can enjoy the same excellent performance characteristics as the company's traditional absorbers, with several new advantages. FlexSorb is a special absorber treatment that allows an absorber to bend but not break. It's ideal for high traffic areas like chamber doorways and interior walls, or for tests that require an anechoic floor treatment. And, being that FlexSorb is also non-hygroscopic: its weight does not change in the presence of atmospheric moisture.
