Overview
The IOP13 is a 256x192 thermal riflescope from Infitac built for close range use, with a wide 13.5 degree field of view and a focus free optical design. It doubles as a clip on unit or handheld monocular, so one device covers several roles.
Most thermal scopes trade magnification for field of view; this one leans hard toward wide angle awareness over long range reach, at just 1.5x base magnification. That makes it better suited to close quarters and home defense scenarios than distant game. A quick detach mount lets it move between scope, clip on, and handheld use without losing zero, according to the listing.
- 256x192 thermal sensor with 25mK or better NETD
- 13.5 x 10.1 degree field of view at 1.5x base magnification
- Quick detach mount for scope, clip on or handheld use
- AI image enhancement (SRE) for low visibility conditions
Who it's for
Suited to shooters who want one thermal unit that adapts to close range work, whether mounted on a rifle, clipped in front of a day optic, or carried as a handheld monocular. Less suited to hunters who need long distance identification, since the wide field of view favors awareness over reach.
What buyers say
From Amazon customer reviews.
The single review on file calls it easy to use with a simple two button layout (record and a zoom or menu wheel) and highlights the focus free design as the standout feature, noting the image stays sharp switching between 50 and 100 yards without any manual adjustment.
Strengths and trade-offs
Drawn from this product's published specifications.
- Focus free from close range to 100 yards
- Switches between scope, clip on and handheld roles
- Wide 13.5 degree field of view for close quarters awareness
- Can stream to an external display for shared viewing
- Low 1.5x base magnification limits long range use

Performance notes
The focus free design keeps the image sharp from near to far without manual adjustment, which the one review confirms works switching between 50 and 100 yards. A 256x192 sensor with NETD of 25mK or better and AI based image enhancement (SRE) are aimed at improving contrast and detail in low visibility conditions like smoke or fog. Optional wireless streaming to an external display (compatible with DNVS-14 Pro) lets a second person view the feed for around cover aiming.

Questions about the Infitac rifle scopes
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
What is the field of view on the Infitac IOP13?
13.5 x 10.1 degrees at 1.5x base magnification, which Infitac positions as an aid to close range awareness rather than long distance spotting.
Can the IOP13 be used as anything besides a rifle scope?
Yes. The listing describes it working as a standalone riflescope, a clip on unit in front of another optic, a handheld monocular, or paired with a 45 degree offset red dot.
Does the IOP13 need to be refocused at different distances?
No, it uses a focus free design, and the sole review on file confirms the image stayed clear moving between roughly 50 and 100 yards without adjustment.
