DIY Night vision spotter (Vis/NIR) project based on a cascade design...

[Lambda]

Hello !

I dare to come here for presenting to you the beginning of a small DIY project i try to implement on the "corner of my kitchen table". Not exactly thermally/LWIR targeted, i have to admit, but still suitable for NIR observation.... Therefore, suitable for observing also objects with high temperature ... 

Here is a kind of night vision spotter based on a cascade architecture with using two gen 1 tubes: XX1080 "diode" (i would rather say triode) II tube from Philips, formally used in armoured vehicle/panzer periscope.

The "prototype" is made from junk box elements, some little cheap very convenient electronic modules available on Ebay for instances, old optics,...
Here is the part 1: "proof of concept".

Nothing new under the Sun, according the prior art, but a cool challenge for a hobbyist, especially not really well equiped...!



And again, a lot of space for improvements, for sure !
To be continued...

Best regards.

Very impressive diy project

Thank you RO.

But honestly, nothing really sophisticated neither finely crafted  ... But promising and very interesting to try to design with low budget and little means.
My next move will be to use a faster lens well L0 adapted for the first upstream tube and using a relay lens L1 with a higher transmission and if possible aspherical.

To be continued !

Regards.
