| Magnets
The magnet is a major factor in determining the size
of an Isolator. The ultimate size of the magnet is not simply determined
by magnetic field strength, but is influenced by the mechanical
design. Many OFR magnets are not simple (one piece), but are complex
(more than one piece). OFR's computer modeling allows optimization
of the many parameters that affect size, optical path length, total
rotation, and field uniformity.
OFR's US Patent 4,856,878 describes one such design
that is used in several of the larger aperture Isolators for YAG
lasers.
OFR emphasizes that a powerful magnetic field exists
around these Isolators. Do not bring steel or magnetic objects closer
than 5 cm.
OFR will not be responsible for damage to any equipment,
electronics, computer discs, etc., nor for injury to any persons,
or damage to any peripheral equipment or property caused by use
of OFR isolators. For information, contact OFR.

Double-dB Isolators
Most OFR Isolators are available as Tandem Isolators
yielding 60 dB to 75 dB isolation. See IOT models and Price List.

Custom Isolators
Custom micro isolators are based on two of OFR's
patents (4,840,464 and 5,087,984), for example the IO-2D Series
NIR Isolators. Epoxy-free optical path This is a feature of all
OFR Isolators.
