RICO HD 1280 2X 75mm Thermal Weapon Sight



The Rugged Infrared Compact Optic(RICO) HD RS75 Rifle Scope is the first commercially available 1280×1024 resolution thermal weapon sight ever created. You read that right, the legendary thermal image quality produced by a High Definition(1280×1024) thermal sensor is finally commercially available to night hunters in the form of an advanced weapon sight. The InfiRay Outdoor RS75 RICO HD RS75 has an incredible 1,310,720 pixels processed by InfiRay’s proprietary MATRIX III algorithm to create an image so clear, it is almost unbelievable.   

It’s been more than a decade since the leap from 320×240 resolution to 640×512 resolution thermal sensor technology, but the inexorable advancement to 1280×1024 resolution has been approaching quietly in the background. As night hunters we have always wanted more performance out of our optics, but the problem was we couldn’t do that with existing technology which had reached its limits. Through years of research and development by an engineering team of over 500 devoted to sensor innovation, InfiRay Outdoor has unleashed the capabilities that night hunters have only dreamed of. 

The InfiRay Outdoor RS75 maintains many familiar RICO Mk1 characteristics, including a 4-button layout, similar software style and menu functions, and high-speed germanium objective optics. In addition to the tried and true features of the MK1 line, InfiRay Outdoor added several highly requested features to the RS75, including 128gb of internal storage space, an upgraded 2560×2560 AMOLED display, an enhanced microphone, and a recoil mitigating mount for increased durability. 


You may be asking yourself, how much better a 1280 resolution is in relation to a 640 resolution? 640 image quality is incomparable with 1280, because of 640’s obvious inherent technological limitations. In addition to the overall clarity of the sight picture, 1280 resolution offers significant advantages over lower resolution optics, specifically the simultaneous combination of a widened field of view and increased detection range. When compared to 640 devices, 1280 resolution allows for double the field of view, double the detection range, or some combination of both. For many years night hunters have been stuck in a world with limited thermal weapon sight capabilities, but InfiRay’s self-developed groundbreaking sensor technology has now unlocked the key to a thermal scope that can do it all.




The RICO HD offers crystal clear onboard audio recording to compliment captured videos. Increased audio clarity over previous RICO generations allows you to capture a quiet whisper before the shot or the report of a bullet impact hundreds of yards away. 



One of the first things you notice when you look through the RICO HD RS75 is the optical clarity. The eyepiece offers edge to edge image perfection when paired with the 1.03″ 2560×2560 AMOLED microdisplay. The RS75’s orthoscopic eyepiece has also been redesigned with premium components specifically selected to achieve low distortion and edge to edge clarity. This redesigned eyepiece offers a more forgiving eyebox for a more comfortable cheek weld and 60mm of eye relief.


What does it take to unlock the next level of thermal imaging? Four times the resolution of 640 devices, 1,310,720 pixels, a 12 degree horizontal field of view, and a detection range of 3,600 yards make the RICO HD the ultimate thermal weapon sight for any distance. No longer do night hunters have to sacrifice detection range or field of view, you can have it all in one scope for close range, mid range, or longer range shots. 


To get the most out of the first 1280×1024 resolution weapon sight, InfiRay Outdoor built in a suite of best-in-class features including a rail mounted laser rangefinder and compatibility with a custom reticle generator app. Never before has a weapon sight enabled the skilled shooter to be as accurate at night as they are in daylight conditions, until now!

1280 vs 640 in a Nutshell 

The 2 most important optical specifications of any thermal night vision weapon sight are horizontal field of view(HFOV) and detection range. HFOV is an angular measurement of how much of a scene you can see at one time, or “how wide” your sight picture is. Detection range is the farthest distance at which you can detect a man-sized target.  

The RS75 has a 12 degree HFOV, the same field of view most manufacturers classify as a 2X base magnification scope. But, the RS75 has double the detection range(3,600 yards vs 1,800 yards) of any 640 2X(12 degree HFOV) scope. Not only that, but it has 50% more detection range than what some manufacturers classify as a 640 4X(7 degree HFOV) scope while still maintaining 70% more HFOV! 1280 is the only way to maintain or increase FOV and at the same time increase the detection range. There simply is no other way to accomplish this which is why 1280 is such a game changer.
