Xenonics SuperVision Question??

Post by andybig » 17 Apr 2015, 13:22

Iv just got hold of another Xenonics SuperVision hand held spotter.
For those who dont know what they are, here is a link.
http://www.xenonics.com/SuperVision/

Its a digital spotter with 4 X zoom and a very good 1280 x 780 near eye display.

I first got my hands on a supervision back in 2006 when these were leaps and bounds ahead of everything else.
Sadly i sold the first one and then the prices went sky high (at an over priced $1,500 US dollars)

But they still out perform any digital spotter iv seen on the market with a near eye display.

Now i want to upgrade the front lens to a 75mm tv lens. The stock lens is about 2 X magnification.
The problem is the C mount thread is deep into the housing and a normal C mount lens is to short to screw in?

My only idea is to fit a M42 adaper and lens. The M42 to C mount adapter needs to have a longer thread on the C mount side.
I did see a supervision converted to have a C mount lens once, but have no idea how it was done?

No ideas to help you Andy but there is likely to be a focal length issue with longer threads.

Whats the standard focal length/distance from a CCD to the back lens of a C mount lens?

It's reputed to be 17.something mm lol - but I have never found that to be the case with Cine or TV lenses - more like 11 to 12mm has proved to be the length for me.

standard distances are 17.5mm for c-mount and 12.5mm for cs-mount measured from the flange to the surface of the sensor.
