Line 1: The '''~~Resistive [[opto-isolator]]~~vactrol''', ~~'''photoresistive~~resistive opto-isolator~~'''~~ or ~~'''vactrol'''~~photoresistive opto-isolator in its simplest form, the ~~analog~~analogue optoisolator consists of a [[LED]] and a [[light-dependent resistor]] (LDR) in the same package: light output from the LED varies as the current passing through it; the light strikes the LDR, varying its resistance in turn; in effect this gives a current-controlled resistor. An early manufacturer of these devices was Vactec Inc, who used the trademark ''Vactrol'', and this has since largely become genericized to cover all such available devices, whoever might make them. Through acquisitions etc., Vactec became part of Perkin Elmer, and recently it appears the Vactrol trademark has passed to a company called 'Excelitas'.
