NocPix LUMI H35R Thermal Imaging Monocular with LRF

At the heart of the LUMI H35R is a 640×512 thermal detector with a 12μm pixel pitch. This high-resolution sensor gives the H35R substantially more thermal image information than the 384×288 L-series LUMI models.

The additional resolution is particularly valuable when scanning a large area, examining smaller heat sources or applying digital magnification. More sensor pixels help preserve useful detail as the image is enlarged.

Thermal sensitivity is rated at ≤18mK NETD. NETD describes the detector's ability to distinguish very small differences in temperature, with a lower figure representing greater sensitivity.

High thermal sensitivity is particularly useful when the temperature difference between an animal and its surroundings is small, including damp, foggy, overcast or otherwise low-contrast conditions.

The defining feature of the H35R is its integrated laser rangefinder. NocPix specifies a ranging capability of up to 800 metres, allowing distance information to be obtained directly through the thermal monocular.

This solves one of the limitations of a conventional thermal spotter. Thermal imaging can reveal a heat source extremely effectively at night, but judging distance through a thermal image alone can be difficult because many of the normal visual depth cues are reduced.

With the H35R, you can locate the heat source thermally and then measure its distance without lowering the monocular and reaching for a separate rangefinder.

The two figures should not be confused. Detection range describes the thermal system's ability to detect that a heat source is present, while LRF range describes the maximum specified distance over which the laser ranging system can measure.

The LUMI H35R also supports ballistic calculation, building on the distance information provided by the integrated laser rangefinder.

Rather than functioning purely as a thermal spotter with a separate distance display, the H35R can use ranging information as part of its ballistic functionality when correctly configured.

This makes the H35R particularly attractive to users who want a compact thermal observation device with more advanced ranging functionality than a conventional non-LRF monocular.

The H35R uses a fast 35mm F0.9 germanium objective lens. The F0.9 aperture is designed to transmit a high level of infrared energy to the thermal detector, helping the sensor extract useful thermal information from the scene.

The combination of the 35mm lens and 640×512 detector produces 2.5× base magnification and a wide 12.5° × 9.4° field of view.

At 100 metres, this corresponds to an observed area of approximately 22 metres × 16 metres.

This is an important part of the H35R's appeal. Rather than using excessive native magnification that makes locating moving animals difficult, it retains a generous viewing area while still providing enough base magnification to examine a detected heat source.

The H35R begins at 2.5× native magnification and provides digital magnification up to 20×.

The relatively low starting magnification works particularly well for scanning because a larger area remains visible through the monocular. Once a heat source is located, additional magnification can then be applied for closer examination.

NocPix specifies a maximum thermal detection range of up to 1,800 metres using a standard 1.7m × 0.5m target at P(n)=99%.

This is a detection figure rather than an identification distance. The range at which an animal can be recognised or positively identified will be shorter and varies according to target size, weather, thermal contrast and atmospheric conditions.

NocPix's Reality+ image processing works with the H35R's 640×512 detector to enhance the presentation of thermal detail and reduce unwanted image noise.

The H35R also incorporates electronic image stabilisation. Small movements that are relatively unobtrusive at base magnification become increasingly obvious as digital zoom is applied, so EIS can be particularly useful when examining more distant heat sources from a handheld position.

A 50Hz refresh rate keeps movement smooth when sweeping across a landscape or following moving wildlife.

The thermal image is presented through a 1024×768 AMOLED display.

AMOLED technology provides high contrast and deep blacks, complementing the high-resolution thermal detector and helping fine temperature differences remain clearly presented through the eyepiece.

The H35R also features a large exit pupil arrangement designed to make eye placement comfortable during repeated handheld scanning.

The NocPix LUMI H35R uses a removable rechargeable 18650 Li-ion battery rather than relying solely on a permanently installed internal battery.

This is particularly useful during longer observation sessions because a discharged cell can be replaced with a charged compatible spare rather than waiting for the entire monocular to recharge.

The LUMI battery compartment also incorporates reverse-polarity support, making battery replacement easier in darkness because the compatible cell can power the device regardless of which way it is inserted.

Battery Type	Replaceable rechargeable 18650 Li-ion
Battery System	Removable with reverse-polarity support
External Power	5V USB Type-C

Operating time varies according to ambient temperature and use of power-intensive functions including Wi-Fi, recording and the laser rangefinder. A compatible spare 18650 battery can be carried for longer sessions.

The LUMI H35R includes 32GB of internal memory and supports both thermal photography and video recording.

A built-in microphone provides audio support for compatible video recordings, allowing observations to be documented without needing a separate recording device.

Wi-Fi connectivity also allows compatible mobile-device functionality through the NocPix ecosystem.

Despite combining a 640×512 detector, 35mm F0.9 objective and integrated laser rangefinder, the H35R retains the compact handheld format that defines the LUMI series.

This makes it particularly suitable for users who want high-end thermal performance but do not want to carry a substantially larger thermal monocular during long periods in the field.

The H35R carries an IP67 ingress-protection rating for resistance to dust and water and is designed to operate across demanding outdoor temperature conditions.

The H35 and H35R are closely related models. Both use a 640×512, 12μm thermal sensor, ≤18mK NETD sensitivity and a fast 35mm F0.9 objective lens.

They also provide the same 2.5× base magnification and wide 12.5° × 9.4° field of view.

The major difference is ranging capability.

LUMI H35	640×512 | 35mm F0.9 | No integrated LRF
LUMI H35R	640×512 | 35mm F0.9 | Integrated LRF up to 800m

The L35R provides a lower-cost route into a 35mm LUMI with an integrated laser rangefinder, while the H35R upgrades the core thermal imaging system.

LUMI H35R	640×512 sensor | 2.5× base magnification | 12.5° × 9.4° FOV
LUMI L35R	384×288 sensor | Higher base magnification | Narrower field of view

The H35R's 640×512 detector contains substantially more thermal pixels, providing greater image information and allowing the 35mm lens to deliver a much wider viewing area.

The L35R is attractive if price and higher native magnification are priorities. The H35R is the stronger option if image resolution, wide-area scanning and overall thermal performance matter more.

LUMI P13 — compact entry-level LUMI designed around a short 13mm objective and wide-area observation.

LUMI L35 — 384×288 resolution with a 35mm lens and higher native magnification for users who do not require an LRF.

LUMI L35R — combines the 384×288 L-series thermal platform with integrated laser ranging.
