Thank you Encap! RB, I liked the Gary Powers story, wish it were true. I'm going to need an adapter to put this thing on the end of a M9 lens.
Edit, back to add:
I wrote them and then googling found this:
http://www.tobyhanna.army.mil/mission/c4isr_mission/EONV.pdf: Electro-Optics/Night Vision.
I was hoping it was a night vision unit, I have some Gen. 1 light amplification tubes which would probably work well with this. The reason I believed it was probably NV was the output end (or input if used as an expander), it is much like another NV lens assembly I have, but that one is much smaller.
I don't know what the big difference might be between a NV telescope and any other telescope, except perhaps the field of view is wider for a given lens diameter, does anyone know? Is there a difference on the coating? I will have to ask more questions once the manufacturer answers, I got an out of office until Sept 12 reply.
With the "Laser" marking on the side, I'm wondering if this is part of a LIDAR system but I have doubts a LIDAR would use a light intensifier tube, no way to measure return nanosecond pulses with that. In that case, the back side of this unit is wrong for a simple detector and this sure appears to have been designed for a NV tube or perhaps a special CCD camera chip, but I've never seen a camera chip wide enough to be used with the short FL 2 inch diameter back aperture this thing has.
