ETS-Lindgrens ClearShield S-Glass RF Shielded Windows Give New Meaning to Visibility

CEDAR PARK, TEXAS, December 3, 2020 - ETS-Lindgren's ClearShield S-Glass Radio Frequency (RF) Shielded Windows give new meaning to the visibility offered at Magnetic Resonance Imaging (MRI) facilities.  S-Glass features a dynamic privacy option incorporated directly in the glass, eliminating the need for blinds or ancillary window coverings. ClearShield S-Glass RF Shielded Windows offer a natural, clean aesthetic to the MRI facility, elevating patient comfort and care.  At the same time, the RF shielding treatment in the window protects the MRI facility and personnel from potential adverse effects that may affect the quality of both patient care and the images produced by the magnet.


ClearShield S-Glass uses unique Liquid Crystal (LC) technology embedded in the window's glass.  S-Glass enables MRI facility personnel to convert the glass from transparent to opaque easily, with a simple switch.  Further, ETS-Lindgren's S-Glass includes a DMX controller providing the ability to set and change the level of opaqueness of the glass. 


"We've been providing RF shielding of MRI facilities for decades now, and the challenge remains the same deliver high quality shielding to protect the magnet and ensure high quality images while at the same time provide an attractive, calming environment for patients and MRI personnel," said Joel Kellogg, ETS-Lindgren's Director of Business Development for Healthcare, Industry, and Government.  "With ClearShield S-Glass, we can do both.  MRI facility management are assured the magnet performance is not compromised with the addition of a window, while the appearance of the facility is enhanced.  MRI personnel can easily provide privacy when needed, and a clear view when visibility is preferred.  The environment can be changed quickly depending on the desired patient care."


ClearShield S-Glass is available on all ETS-Lindgren windows, including windows located on RF Shielded Doors, and ClearShield RF Shielded Windows. These high-visibility architectural windows expand the horizons of an MRI shielded enclosure to provide the ultimate patient care experience.  All ClearShield S-Glass RF Shielded Windows are available in standard as well as custom sizes to meet customer-specific installation requirements.
