HIKMICRO Lynx LH35 3.0 Thermal Monocular 35mm 384px

The Lynx LH35 3.0 incorporates a 384 × 288 uncooled VOx thermal detector with a 12μm pixel pitch, providing 110,592 native thermal pixels.

The detector is designed to identify differences in infrared radiation emitted by animals, objects and their surroundings, allowing observation in daylight, low light and complete darkness.

With a manufacturer-stated Noise Equivalent Temperature Difference (NETD) below 15mK, the LH35 can distinguish very small temperature differences under specified test conditions.

Lower NETD values generally indicate improved sensitivity to subtle thermal variations, which can help reveal animal outlines against vegetation, ground features and other backgrounds.

The combination of 384 × 288 resolution and below-15mK sensitivity provides a strong foundation for observing heat signatures at longer distances.

Actual image quality depends on temperature contrast, atmospheric humidity, weather, subject size and observation distance.

The LH35 3.0 features a 35mm F1.0 objective lens, providing the longest focal length in the LH15, LH25 and LH35 Lynx 3.0 models.

The longer objective focal length produces greater native magnification and a narrower field of view, making the LH35 particularly suitable for observing distant thermal subjects.

Unlike the focus-free LE and smaller LH models, the LH35 features a manual objective focus ring.

This allows the user to refine the thermal image for different observation distances, helping achieve the clearest possible view of a subject.

HIKMICRO specifies a minimum focusing distance of approximately 3.5 metres.

The 35mm F1.0 objective is particularly useful when scanning large fields, open farmland, moorland and distant woodland edges where longer-range observation is a priority.

HIKMICRO specifies a maximum thermal detection distance of up to 1,800 metres for the Lynx LH35 3.0.

This is 600 metres greater than the manufacturer's stated 1,200-metre detection range for the LH25 3.0.

The detection figure is based on a standard reference thermal target under specified manufacturer test conditions.

Detection means establishing the presence of a heat signature. It does not guarantee that the subject can be positively identified at the maximum stated distance.

The combination of a 35mm objective, 384 × 288 detector and high thermal sensitivity makes the LH35 particularly effective for scanning open landscapes and locating distant thermal subjects.

Actual detection and identification distances depend on target size, temperature contrast, weather, humidity and surrounding terrain.

The Lynx LH35 3.0 provides an angular field of view of 7.5° × 4.6°, equivalent to approximately 13.1 × 8.0 metres at a distance of 100 metres.

This narrower viewing area is designed for more concentrated observation of distant subjects rather than scanning the widest possible area.

The monocular has 3.4× base magnification and supports up to 8× digital zoom, providing an overall magnification range from 3.4× to 27.2×.

The higher base magnification allows distant subjects to appear larger before digital magnification is applied.

Digital zoom enlarges a selected portion of the thermal image but does not increase the detector's native resolution.

The LH35 is therefore particularly suitable for users who prioritise observing distant heat signatures across larger open areas.

The LH35 3.0 features HIKMICRO's Image Pro 3.0 thermal image-processing technology.

The system is designed to refine the presentation of thermal images by improving perceived contrast, edge definition and fine detail.

Image Pro 3.0 works alongside the 384 × 288 thermal detector and high-sensitivity thermal module to provide a more detailed viewing image.

This can be particularly useful when observing animals against vegetation, uneven terrain and backgrounds with relatively little temperature contrast.

Image processing enhances the displayed image but does not increase the physical resolution of the thermal detector.

The HIKMICRO Lynx LH35 3.0 incorporates Zoom Pro digital image-enhancement technology.

Zoom Pro is designed to improve the perceived clarity of thermal images when digital magnification is used.

Increasing digital zoom normally enlarges the existing sensor image, which can make image noise and individual pixels more noticeable.

Zoom Pro applies additional image processing to help maintain useful visual detail at higher magnification settings.

This complements the LH35's 3.4× base magnification and 384 × 288 thermal detector, particularly when examining distant heat signatures.

Zoom Pro does not increase the physical number of thermal pixels captured by the sensor.

The LH35 3.0 includes HIKMICRO Sync Pro technology and the manufacturer's Shutterless Image System (HSIS).

Conventional thermal imaging devices may periodically interrupt the viewing image while performing mechanical shutter calibration.

HSIS is designed to reduce these interruptions, helping maintain a continuous thermal image when observing moving subjects.

Sync Pro is part of the Lynx 3.0 imaging platform and is designed to improve the responsiveness of the viewing experience.

These technologies complement the device's 50Hz refresh rate, supporting smooth thermal observation when scanning or following movement.

The Lynx LH35 3.0 features a 0.49-inch AMOLED display with a resolution of 1920 × 1080 pixels.

This high-resolution viewing display presents the processed thermal image, digital magnification and device menus through the eyepiece.

Six selectable thermal colour palettes are available:

• White Hot
• Black Hot
• Red Hot
• Red Monochrome
• Green Monochrome
• Fusion

Different colour palettes can help users adapt the viewing image to changing observation conditions and personal preference.

The display also supports brightness, contrast and warm or cold tone adjustment.

Eyepiece specifications include 20mm eye relief, a 6mm exit pupil and dioptre adjustment from -5D to +3D.

The LH35 3.0 includes additional observation functions designed to improve convenience and situational awareness.

Picture-in-Picture displays a magnified portion of the thermal image while retaining the surrounding field of view.

This allows users to examine a distant heat signature without completely losing awareness of the wider scene.

Hot Track helps identify warmer areas within the thermal image, making it easier to locate thermal subjects.

The monocular also supports software-based distance measurement, providing an estimated distance using configured reference information.

This function is not equivalent to an integrated laser rangefinder and should not be relied upon for precision ranging.

Standby mode allows the device to remain ready for use between observation periods.

The HIKMICRO Lynx LH35 3.0 operates using a replaceable rechargeable 18650 lithium-ion battery.

The standard manufacturer accessory package includes two rechargeable 18650 batteries and a compatible battery charger.

This allows one battery to be installed in the monocular while the second is kept as a spare for extended observation sessions.

• Battery type: Rechargeable 18650 lithium-ion
• Battery system: Removable and replaceable
• Rechargeable batteries included: 2
• Battery charger included: Yes

The Lynx LH35 3.0 combines a powerful 35mm objective lens with a compact handheld design suitable for outdoor observation.

Its dimensions are approximately 169.6 × 53.6 × 49.5mm, with a manufacturer-stated weight of 354.5g including battery.

Despite its longer objective lens, the monocular remains convenient to carry during countryside walks, wildlife observation and longer scanning sessions.

The housing has an IP67 ingress protection rating, providing resistance to dust and temporary water immersion under the conditions specified by the rating.

HIKMICRO specifies an operating temperature range from -30°C to +45°C.

The manual focus ring, replaceable battery system and lightweight construction make the LH35 suitable for frequent use across open countryside and changing observation distances.

The LH35 3.0 and LH25 3.0 share the same 384 × 288 thermal detector and high-sensitivity imaging platform, but differ in objective lens size, base magnification and detection range.

The LH35 3.0 provides greater native magnification and a 50% longer manufacturer-stated detection range than the LH25 3.0.

The LH25 offers a wider field of view, making it more suitable for customers who regularly scan closer or more enclosed areas.

For longer-range observation across open countryside, the LH35 is the more distance-focused option.
