NocPix QUEST H50R Thermal Imaging Binoculars with LRF

The QUEST H50R is the longer-distance 640×512 option in the QUEST range. It is particularly well suited to users who regularly observe across open fields and larger areas where greater image scale at distance is more useful than maximum field of view.

Its 50mm F1.1 lens and 4× base magnification provide a more focused view than the H35R. The trade-off is a narrower 15 × 12m field of view at 100m, compared with 22 × 18m on the H35R.

The H50R is therefore not simply a "better H35R". Both use the same 640×512 detector but are optimised differently. H35R prioritises wider scanning, while H50R places greater emphasis on longer-distance observation.

Choose the H50R if you want: high-resolution 640×512 imaging, 4× base magnification, strong long-distance capability, integrated LRF and comfortable binocular viewing.

L35R: The most accessible QUEST, using a 384×288 sensor and 35mm lens.

H35R: Moves to a 640×512 sensor while retaining a 35mm lens, providing substantially more resolution and a very wide field of view.

H50R: Uses the same 640×512 sensor as the H35R but moves to a 50mm lens and 4× base magnification for greater long-distance emphasis.

S50R: The flagship model, combining a 1280×1024 detector with a 50mm lens for maximum thermal detail and an exceptionally wide field of view.

The H35R and H50R share the same 640×512, 12μm thermal sensor, ≤15mK sensitivity and 60Hz refresh rate. Choosing between them is mainly about field of view versus longer-distance image scale.

H35R: 35mm F0.9 lens, 3× base magnification and approximately 22 × 18m field of view at 100m. It is the stronger option for wide-area scanning and mixed terrain.

H50R: 50mm F1.1 lens, 4× base magnification and approximately 15 × 12m field of view. The larger focal length makes distant subjects appear larger within the image and increases the manufacturer's stated detection range to approximately 2,600m.

Choose H35R for wider viewing and maximum versatility. Choose H50R if longer-distance observation is more important.

The H50R and flagship S50R both use a 50mm F1.1 objective lens, making the difference between them particularly easy to understand: the major upgrade is the thermal sensor.

The H50R uses a 640×512 detector containing 327,680 thermal pixels. The S50R increases this to 1280×1024, or 1,310,720 thermal pixels — exactly four times the pixel count.

That additional resolution also allows the S50R to start at just 2× magnification while providing an exceptionally wide 30 × 24m field of view at 100m. The H50R starts at 4× and provides 15 × 12m.

Choose H50R if you want excellent 640×512 performance and stronger value. Choose S50R if maximum image information, wider viewing and flagship thermal performance justify the additional investment.

The major advantage of the QUEST format is comfortable two-eye viewing. This provides a more natural binocular-style viewing experience during prolonged thermal observation.

The binocular body also provides a stable two-handed grip, while dual displays avoid continuously relying on one eye when scanning for extended periods.

A thermal monocular remains attractive where minimum size and weight are the priorities. QUEST binoculars are particularly appealing where viewing comfort and prolonged observation matter more.

NETD measures how effectively the thermal detector can distinguish very small differences in temperature. In general, a lower figure indicates greater thermal sensitivity.

The QUEST H50R is rated at ≤15mK, helping it retain subtle thermal and environmental detail when temperature differences between the subject and surroundings are small.

R+ image processing is NocPix's image-processing technology designed to optimise thermal detail, contrast and overall image presentation.

Electronic Image Stabilisation (EIS) helps reduce visible image movement during handheld observation, providing a steadier thermal image.

This is particularly useful on the H50R because its higher 4× base magnification can make small handheld movements more noticeable than on wider-view models.

The QUEST H50R incorporates a concealed laser rangefinder with a manufacturer-specified maximum range of up to 1,000 metres.

Integrating the LRF directly into the binocular body provides convenient distance measurement without requiring a separate handheld rangefinder.

NocPix specifies a detection range of approximately 2,600 metres for the QUEST H50R under its stated test conditions.

Detection is not the same as identification. At very long distances the thermal sensor may detect that a heat source is present without providing enough image detail to determine exactly what it is.

Actual useful viewing distance varies according to subject size, weather, thermal contrast and environmental conditions.

NocPix's standard manufacturer warranty provides:

• 3 years warranty on the main device
• 2 years warranty on the battery
• 10 years warranty on the thermal detector

What sensor does the QUEST H50R use?
It uses a 640×512, 12μm thermal detector with ≤15mK thermal sensitivity and a 60Hz refresh rate.

How far can the QUEST H50R detect?
NocPix specifies a detection range of approximately 2,600m under its stated test conditions. Detection should not be confused with identification range.

Does the QUEST H50R have an LRF?
Yes. It has an integrated concealed laser rangefinder with a manufacturer-specified range of up to 1,000m.

What is the difference between H35R and H50R?
Both use 640×512 sensors. H35R uses a 35mm lens and provides a wider field of view, while H50R uses a 50mm lens and 4× base magnification for greater long-distance emphasis.

What is the difference between H50R and S50R?
Both use 50mm F1.1 lenses, but the S50R increases sensor resolution from 640×512 to 1280×1024. This gives the S50R four times as many thermal pixels and allows a much wider field of view.

Which QUEST is best for longer distances?
The H50R is the longer-distance-focused 640×512 model. The S50R sits above it as the flagship 1280×1024 option.

Is the QUEST H50R waterproof?
The QUEST series carries an IP67 protection rating.

How long is the NocPix warranty?
NocPix's standard warranty provides 3 years on the main device, 2 years on the battery and 10 years on the thermal detector, subject to manufacturer terms.

The NocPix QUEST H50R uses a dual-battery system, combining a built-in rechargeable battery with a removable 18650 rechargeable battery.

The external 18650 can be replaced in the field without interrupting use, making it easy to extend operating time during longer sessions. NocPix states approximately 6 hours of operating time under normal use, although actual runtime will vary depending on temperature and use of features such as the laser rangefinder, Wi-Fi and recording.

Two 18650 rechargeable batteries are supplied, giving you a spare external battery ready to swap when required.
