NocPix ACE H50 Thermal Imaging Scope

At the heart of the ACE H50 is a 640×512 thermal detector with a 12μm pixel pitch. Compared with lower-resolution 384×288 thermal systems, the 640 sensor captures substantially more thermal information, helping produce a more detailed image and giving the user more information when observing distant heat sources.

The detector is rated at ≤15mK NETD thermal sensitivity. NETD describes the detector's ability to distinguish small differences in temperature; lower values indicate greater sensitivity to subtle thermal variations.

This becomes particularly useful when the target and its surroundings are at similar temperatures, such as during damp, misty, overcast or mild conditions when thermal contrast can be reduced.

The sensor operates at 60Hz, helping moving targets and fast scanning appear smooth rather than noticeably stepping between frames.

The H50 pairs its 640×512 detector with a 50mm F0.9 germanium objective lens. The fast F0.9 aperture allows a high level of infrared energy to reach the detector, complementing the ≤15mK sensor.

The 50mm focal length gives the H50 a 3× starting magnification and an 8.8° × 7.0° field of view, equivalent to approximately 15.4m × 12.3m at 100 metres.

NocPix specifies a maximum thermal detection range of up to 2,600 metres using a standard 1.7m × 0.5m target at P(n)=99%.

Detection range should not be confused with identification range. At the maximum detection distance, the scope is intended to establish that a heat source is present. The distance at which the target can be recognised or positively identified will be shorter and varies with target size, weather, atmospheric conditions and thermal contrast.

The ACE H50 provides a 3× base magnification with an overall magnification range of 3–24×.

A particularly distinctive ACE feature is its ocular zoom system. Rather than relying exclusively on electronic enlargement of the thermal image, the ACE incorporates an adjustable optical eyepiece system with 1–3× ocular zoom.

This gives the shooter another way to adjust the apparent viewing scale through the eyepiece and is one of the major features distinguishing the ACE platform from more conventional thermal riflescope designs.

The H50's combination of a 50mm objective and 3× base magnification makes it particularly well suited to open ground and medium-to-longer-range thermal observation.

The H50 uses a high-resolution 2560×2560 AMOLED display as part of NocPix's Vision+ viewing system.

The unusually high display resolution is designed to provide a detailed, immersive view through the eyepiece and make full use of the information supplied by the 640×512 thermal sensor.

Display Type	AMOLED
Display Resolution	2560×2560
Eye Relief	50mm
Exit Pupil	8mm
Dioptre Adjustment	-5D to +5D

NocPix combines the H50's high-resolution detector with its Reality+ image-processing technology to improve image presentation, detail and thermal contrast.

The ACE platform also uses a shutterless design. Conventional thermal devices may periodically interrupt the image while performing calibration. The ACE system is designed to minimise disruption to the viewing experience, which is particularly useful when continuously observing or tracking a moving target.

Together with the H50's 60Hz sensor, the result is a thermal image designed to remain fluid and usable during active observation.

The ACE H50 uses a dual-power arrangement rather than relying solely on one removable battery.

Inside the scope is a built-in 4000mAh rechargeable battery. This is supplemented by a replaceable rechargeable 18650 battery, giving the scope two power sources.

NocPix specifies a maximum operating time of up to 7 hours at 22°C. Actual operating time varies according to temperature and the frequency with which functions such as Wi-Fi, photography and video recording are used.

Internal Battery	Built-in 4000mAh rechargeable battery
Replaceable Battery	Rechargeable 18650 Li-ion battery
Maximum Stated Runtime	Up to 7 hours at 22°C
External Power	5V USB Type-C

The dual arrangement is useful during longer sessions because the removable 18650 can be exchanged while the integrated battery provides an additional onboard power reserve.

The ACE H50 incorporates 64GB of internal storage and supports photography, video and audio recording.

Recoil-activated video recording allows the scope to automatically capture footage around the moment a shot is detected, reducing the need to manually begin recording before every opportunity.

A built-in Gallery function allows captured footage to be reviewed directly through the device, while Wi-Fi and app support provide connectivity with a compatible mobile device.

This makes the recording system useful both for retaining memorable footage and for reviewing thermal observations after use.

The NocPix ACE H50 uses a conventional 30mm tube mounting system.

This means the scope can be installed using suitable 30mm scope rings rather than requiring a proprietary integrated rail mount.

The traditional riflescope-style format gives considerable flexibility when choosing ring height and positioning the optic to achieve the correct eye relief on a compatible platform.

The ACE H50 is designed as a dedicated thermal riflescope rather than a handheld monocular adapted for weapon use.

NocPix specifies recoil resistance of up to 6,000 joules for the ACE platform. The body is constructed from high-strength aluminium alloy and the scope carries an IP67 ingress-protection rating.

Its specified operating-temperature range is -20°C to +50°C, allowing the scope to operate across a broad range of outdoor conditions.

The ACE H50 and H50R share the same core 640×512, 12μm thermal sensor, ≤15mK sensitivity, 60Hz refresh rate, 50mm F0.9 objective lens, 3–24× magnification and 2,600m stated detection range.

The major difference is ranging.

ACE H50	640×512 | 50mm F0.9 | 3–24× | No integrated LRF
ACE H50R	640×512 | 50mm F0.9 | 3–24× | Integrated Class 1 LRF up to 1,200m

The H50 represents a significant step up from the entry-level ACE L35 in both sensor resolution and longer-range capability.

ACE L35	384×288 | ≤18mK | 35mm F0.9 | 4–16× | 1,800m detection
ACE H50	640×512 | ≤15mK | 50mm F0.9 | 3–24× | 2,600m detection

The H50's 640×512 detector contains substantially more thermal pixels than the L35's 384×288 detector, while its 50mm objective provides greater detection reach.

The L35 starts at a higher 4× native magnification and remains a useful lower-cost option. The H50 is the stronger choice when image detail, thermal sensitivity and overall longer-range performance take priority.

The S60R is the flagship model of the original ACE generation and represents a substantial step up from the H50.

ACE H50	640×512 | ≤15mK | 50mm F0.9 | 3–24× | 2,600m detection | No LRF
ACE S60R	1280×1024 | ≤15mK | 60mm F1.0 | 2–24× | 3,100m detection | 1,200m LRF

The S60R's 1280×1024 sensor contains four times the thermal pixel count of a 640×512 detector. Despite using a longer 60mm objective, it also provides a much wider field of view because of the significantly larger sensor.

The H50 remains the more accessible option for users who want premium 640-resolution thermal performance without paying for the S60R's 1280 sensor and integrated rangefinder.

The ACE H50 belongs to the original NocPix ACE generation. The newer ACE 2 range is a separate next-generation family and should not be confused with this model.

The original H50 remains a high-specification 640×512 thermal riflescope with a 50mm F0.9 lens, ≤15mK sensitivity, 60Hz refresh rate, ocular zoom, dual batteries and the high-resolution 2560×2560 Vision+ display.

The newer ACE 2 family introduces further developments including ≤12mK thermal sensitivity and other platform updates. Whether those upgrades justify moving to ACE 2 depends on the model being compared and the price difference.

For customers comparing generations, the original ACE H50 can therefore remain a particularly strong-value route into the 640×512 ACE platform.

ACE L35 — the more affordable 384×288 model with a 35mm F0.9 lens, 4× base magnification and up to 1,800m stated detection.

ACE H50 — the 640×512, 50mm model for users wanting higher resolution and longer-range performance without an integrated LRF.

ACE H50R — uses the same core 640×512, 50mm thermal platform as the H50 but adds an integrated 1,200m laser rangefinder and ballistic calculation support.

ACE S60R — the flagship original ACE with a 1280×1024 sensor, 60mm lens, wide field of view, 3,100m stated detection and integrated 1,200m LRF.
