The sources said National Instruments, had in the past, worked on major projects like night vision equipment for the armed forces but research work had petered out in recent years.
Phone calls to National Instruments went unanswered today.
Right next to National Instruments is another sick central government-owned PSU -- Bharat Ophthalmic Glass -- a lab which was once at the forefront of materials research but is now in doldrums. This lab, too, is expected to go on the block soon.
