For many years, Opto-Line has supplied high end EMI grids on IR substrates, reticles, and custom patterned optics for defense systems including scopes, laser range finders, target designator systems and other critical applications.  Opto-Line is proud to manufacture parts used for the United States’ defensive systems as we take great pride in our work and service.  The critical nature and accuracy of our patterns cannot be understated.  This is fundamental to the work we do here at Opto-Line.  Our reputation is built upon it and our success depends on it.

EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.

Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. The disturbance may degrade the performance of the circuit or even stop it from functioning. In the case of a data path, these effects can range from an increase in error rate to a total loss of the data.
