H35: Wide-view 640×512 model. A strong choice for scanning larger areas and mixed-distance observation.

H35R: Uses the same core 35mm thermal platform as the H35 but adds an integrated 1,200m laser rangefinder.

H50: Longer-range 640×512 model with a 50mm lens and higher 4× base magnification.

H50R: Combines the longer-range H50 thermal platform with an integrated 1,200m laser rangefinder.

S50R: Flagship VISTA with a 1280×1024 thermal sensor, 2× base magnification and an exceptionally wide 31 × 25m field of view.

Best for wide scanning – VISTA H35:
Choose the H35 if you want high-resolution 640×512 thermal imaging with a wide 22 × 18m field of view and do not need an integrated rangefinder.

Best wide-view model with LRF – VISTA H35R:
The H35R keeps the same wide-view 35mm setup as the H35 but adds integrated laser rangefinding up to 1,200m.

Best for longer-range observation – VISTA H50:
The H50 uses a 50mm F0.9 lens and 4× base magnification, providing greater image scale at distance than the H35 while retaining the 640×512 thermal sensor.

Best long-range 640×512 model with LRF – VISTA H50R:
Choose the H50R if you want the longer-range characteristics of the H50 together with built-in distance measurement.

Best overall image detail – VISTA S50R:
The S50R is the flagship VISTA. Its 1280×1024 thermal sensor contains four times the thermal pixel count of the 640×512 H-series and combines this with a very wide 31 × 25m field of view.

The H35 and H50 both use a 640×512, 12μm thermal detector with ≤15mK sensitivity. The main difference is the objective lens.

H35 – 35mm F0.9: Provides 3× base magnification and a wide 22 × 18m field of view at 100m. This makes it particularly useful for scanning and locating heat sources across larger areas.

H50 – 50mm F0.9: Provides 4× base magnification and a narrower 15 × 12m field of view at 100m. Distant subjects therefore appear larger in the image.

NocPix specifies detection ranges of up to approximately 1,800m for the H35 and 2,600m for the H50.

Choose the 35mm models for wider scanning and the 50mm models for greater reach and image scale at distance.

Within the current VISTA range, the R models include an integrated laser rangefinder.

The H35 and H35R share the same 640×512 sensor, 35mm F0.9 lens, 3× base magnification and 22 × 18m field of view. The H35R adds an integrated laser rangefinder capable of measuring distances up to approximately 1,200m.

The H50 and H50R follow the same principle. Both use a 640×512 sensor and 50mm F0.9 lens, but the H50R adds the integrated 1,200m laser rangefinder.

If you do not require accurate distance measurement, the non-R versions provide the same core thermal imaging configuration. If range information is important, choose the corresponding R model.

The biggest difference between the S50R and H50R is the thermal detector.

The H50R uses a 640×512 detector, containing 327,680 thermal pixels. The S50R uses a 1280×1024 detector, containing 1,310,720 thermal pixels.

That gives the S50R four times as many thermal pixels. This provides substantially more native image information and helps retain finer detail, particularly when subjects are smaller or digital magnification is applied.

The S50R also starts at just 2× base magnification and provides a very wide 31 × 25m field of view at 100m. The H50R starts at 4× and provides a narrower 15 × 12m view.

Choose the H50R if you want premium 640×512 long-range performance and integrated rangefinding. Choose the S50R if maximum thermal detail and a much wider scanning view are the priorities.

Thermal sensor resolution tells you how many individual thermal measurement points are used to create the image.

640×512: Used by the H35, H35R, H50 and H50R. This provides 327,680 thermal pixels and delivers a high level of thermal detail for premium handheld observation.

1280×1024: Used by the S50R. This provides 1,310,720 thermal pixels, which is four times the pixel count of a 640×512 detector.

Higher native resolution is particularly valuable when distinguishing smaller details, viewing more distant subjects or applying digital magnification while retaining useful image information.

NETD measures how small a temperature difference the thermal detector can distinguish. A lower NETD figure generally indicates greater thermal sensitivity.

The VISTA range's highly sensitive thermal detectors are designed to reveal subtle temperature differences in demanding, low-contrast conditions such as damp weather, mist or environments where the background temperature is relatively close to that of the subject.

Sensor resolution and thermal sensitivity should be considered together. Resolution determines how much spatial detail is captured, while NETD influences how effectively small temperature differences can be separated.

Field of view tells you how much terrain is visible through the thermal monocular at one time.

A wider field of view makes it easier to scan quickly, locate moving heat sources and maintain awareness of the surrounding area. A narrower field of view generally accompanies greater base magnification, making distant subjects appear larger.

The H35 and H35R provide approximately 22 × 18m at 100m, while the H50 and H50R provide approximately 15 × 12m. The flagship S50R provides approximately 31 × 25m.

This is why the H35 models are particularly strong for scanning, the H50 models are more distance-focused, and the S50R manages to combine an exceptionally wide view with very high native thermal resolution.

Manufacturer-stated detection range indicates the distance at which a thermal device can detect that a sufficiently large heat source is present under defined test conditions.

NocPix specifies the H35 platform at up to approximately 1,800m and the H50 platform at up to approximately 2,600m against its standard test target.

Detection is not the same as identification. A thermal monocular may show that a heat source is present at a long distance without providing enough detail to determine exactly what the subject is.

Real-world usable distance varies according to target size, weather, vegetation, thermal contrast, atmospheric conditions and the amount of digital magnification being used.

A defining feature of the NocPix VISTA range is its high-resolution 2560×2560 AMOLED display and immersive circular viewing presentation.

The display is designed to provide a large, detailed and comfortable image, helping make the VISTA range particularly suitable for users who spend longer periods scanning and observing through their thermal monocular.

The high-resolution display is especially valuable on the flagship S50R, where it complements the exceptionally detailed 1280×1024 thermal detector.

NocPix VISTA thermal monoculars use a practical replaceable rechargeable battery system designed for extended use in the field.

A major advantage is that the VISTA package includes 2 × rechargeable IBP-7 battery packs. This allows you to carry a charged spare and exchange the battery in the field rather than having to stop using the monocular while the first battery is recharged.

The H-series IBP-7 battery has a capacity of 4400mAh, with NocPix specifying maximum operating time of approximately 5.5 hours under its stated test conditions for the H35 and H50 platforms.

Actual operating time varies according to temperature and use of functions such as video recording and wireless connectivity.
