[1] Faraday rotator: An optical isolator consists of a magnetic garnet crystal having a Faraday effect, a permanent magnet for applying a designated magnetic field, and polarizing elements that permit only forward light to pass while blocking backward light. With its extra measure of ozone resistance and low gas permeability, Hydrin is said to serve well in gaskets, oil field specialties, hoses, diaphragms, pump and valve parts, belting, vibration isolators, etc. All of that equipment is protected by a Channel Microwave-made device called an isolator, about the size of a harmonica with a cost of about $1,000 for a basic model. |
