Hello All,
I was rummaging through my parts and found this curious looking component.  I tried searching the web for information on it to no avail.  It is labelled NSL-06-005.  It looks to be some sort of opto-gizmo.  It's well built and appears to be hermetically sealed.  Please have a look at the pictures I uploaded.  Any Ideas?  Thanks.
Eric

It has two leads, the same length, no tabs or flat spots.  Nothing indicating polarity.  I measure between 29K - 70K with my finger over the window...as best I can and hold test leads.  I measure both directions and its about the same.

Okay... in a breadboard, with black tape over the window it measures open.  Remove the black tape and resistance is 6K.  So it looks like a NASA grade cds cell.
