Didn't want to hijack the PAS-13 thread so here's a fresh one...
Was reading up on the blurb about the new lightweight versions of the PAS-13 unit and saw mention about the combined use of thermal and image intensification as complimentary technologies. Since I was reading up on a weapon sight, the natural thought occurred: Can the PSQ-20 be used as a weapon sight on say a Mk-12? I've read the current wisdom on using those particular image intensifier tubes on rifles no larger than 5.56mm, but I'm rather uninitiated when it comes to thermal viewers. |

Yes, but you need a TCAD or other OOB system instead of the usual laser on your rifle, and you leave the PSQ-20 on your noggin where it's designed to go :) For what it's worth, there are a series of newly developed thermal fusion riflescopes coming out - but the likelyhood of any of us outside of the .mil seeing them is pretty low. For the most, that means we have access to thermal riflescopes, which are really plummeting in price, and to IIT's but I don't know of any commercially available fusion riflescopes at this point in time.

TCAD - Thermal Collimated Aiming Device (thermal laser) OOB - Out of Band And no, the PSQ-20 and similar thermal fusion monoculars are designed for headborne use and are not designed to be weapon mounted. Not only do they require external battery packs, but I doubt they've been hardened for the shock of a weapon they're not designed to be mounted to. They also do not contain any sort of reticule program or zeroing ability, and because it's a thermal optic it can't be clipped on behind a day optic, nor can it be collimated to work in front of a day optic. |

I'd say no. If you use "up front" like clip-on, then the boresight will be off as they are 2 different apertures. If you use it "behind" day scope, it won't either - and you can take my word for it...as for specific reason, I have to withhold that info (as it's a tactical/technological reason)....but if you own a FLIR, it doesn't take long to figure out why. I know that NG had a catadioptric fusion weapon sight, which is coaxial in nature of the two bands and has a reflective objective. It's a clever design....and I'm sure it's a matter of time they'll turn it into a clip on as soon as they can figure out the relatively low-res display issue, comparing to tube resolution. Think of the design of PVS-4 and where the secondary reflector (the center spider mount) is, you mount a FLIR there. I'm sure though that the FOV can also be problematic, unless they start shrinking the detector pitch down and up the quantum efficiency.

| Eliminate boresight issue, but I'm sure it's a hell of a problem to correct the FOV differences between the FLIR and NV. Another design is that you can separate the bands internally after the objective (sort of like SLR camera design), but you will run into expensive materials, transmission (and possibly coating) and (maybe) packaging issue. |
