[Laser] All Electronics PD-3/4

[Clifford Buttschardt]

Hi everyone.  In some regard I feel like a fool as I was the one that
confirmed All Electronics as the detector supplier last week.  The
foolishness is that I did not get going before all of them were sold!
     At that time mention was made of some narrow band filters gotten from
Haltex Electronics in Mountain View, CA.  They are unavailable now also.
I have quite a few of these filters for 650 nM----OMEGA OPTICAL 650WB40.
Is there anyone needing a couple of these filters for a swap for a single
detector either the PD-3 or PD-4? The filters are in the original envelope.
