NocPix LUMI L35 Thermal Imaging Monocular

The LUMI L35 uses a 384×288 thermal detector with a 12μm pixel pitch. This gives it the same native sensor resolution as the L19, but the longer objective lens provides a very different viewing experience.

Thermal sensitivity is rated at ≤18mK NETD. A low NETD value allows the detector to distinguish smaller differences in temperature, helping preserve useful detail when the temperature difference between an animal and the surrounding environment is reduced.

This is particularly useful during damp, misty, overcast or mild conditions where natural thermal contrast may be lower.

The L35 pairs its 384×288 detector with a 35mm F0.9 germanium objective lens.

The F0.9 aperture allows a high level of infrared energy to reach the detector, while the 35mm focal length gives the monocular 4× base magnification and a narrower 7.5° × 5.7° field of view.

At 100 metres, the L35 shows an area of approximately 13m × 10m. Compared with the L19, this narrower view places more emphasis on distant targets and makes heat sources appear larger before digital zoom is applied.

This makes the L35 particularly well suited to larger fields, open ground and users who prioritise longer-range observation over maximum scanning width.

The NocPix LUMI L35 starts at 4× base magnification and provides digital magnification up to 16×.

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%.

Detection range means the monocular can establish that a heat source is present. Recognition and positive identification occur at shorter distances and depend on target size, weather, atmospheric conditions and thermal contrast.

The combination of 4× starting magnification and 1,800m stated detection makes the L35 a strong option for users who want more reach without moving up to the more expensive 640×512 H35.

NocPix equips the LUMI series with Reality+ image processing designed to improve the presentation of the thermal information captured by the sensor.

The L35 also incorporates electronic image stabilisation, which can help reduce the visual effect of small hand movements during handheld use.

This is especially useful on the L35 because its higher 4× base magnification makes movement more noticeable than on wider-view models such as the L19.

A smooth 50Hz refresh rate helps keep moving targets and panning motion fluid.

The LUMI L35 uses a 1024×768 AMOLED display to present the thermal image through the eyepiece.

AMOLED technology provides strong contrast and deep blacks, helping the thermal image remain clear and easy to interpret.

The optical system also provides 25mm eye relief, a 10mm exit pupil and -5D to +5D dioptre adjustment for comfortable handheld viewing.

Despite its 35mm objective and longer-range focus, the LUMI L35 weighs approximately 335g including its battery.

Its compact body measures around 143 × 47 × 74mm, making it easy to carry in a jacket pocket, pouch or kit bag.

This lightweight format is one of the LUMI range's main strengths. It provides useful detection reach without the bulk traditionally associated with longer-range thermal monoculars.

The NocPix LUMI L35 uses a replaceable rechargeable 18650 Li-ion battery.

The removable design allows a compatible charged spare to be carried and exchanged in the field instead of taking the complete monocular out of use while a fixed internal battery recharges.

NocPix also incorporates reverse-polarity support, allowing easier battery replacement in darkness.

Battery Type	Replaceable rechargeable 18650 Li-ion
Maximum Stated Runtime	Up to 4.5 hours
External Power	USB Type-C

Actual runtime varies with ambient temperature and use of functions such as Wi-Fi, photography and video recording.

The LUMI L35 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 directly through the monocular.

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

The LUMI L35 carries an IP67 ingress-protection rating, helping protect the monocular against dust and water during demanding outdoor use.

NocPix specifies an operating-temperature range of -20°C to +50°C, allowing the L35 to be used across a broad range of seasonal and weather conditions.

The L35 and L19 use the same 384×288, 12μm sensor and the same ≤18mK thermal sensitivity. The difference is almost entirely about lens choice and how that changes the image.

LUMI L19	19mm F0.9 | 2–8× | 13.8° × 10.4° FOV | 980m detection
LUMI L35	35mm F0.9 | 4–16× | 7.5° × 5.7° FOV | 1,800m detection

The L35 and L35R share the same core 384×288 thermal platform, 35mm F0.9 lens, 4× base magnification and 7.5° × 5.7° field of view.

The key difference is that the L35R adds an integrated laser rangefinder, allowing distance to be measured directly through the thermal monocular.

The L35 and H35 both use 35mm F0.9 objective lenses and have the same stated 1,800m detection range, but they behave very differently because of their sensor resolutions.

LUMI L35	384×288 | 4–16× | 7.5° × 5.7° FOV
LUMI H35	640×512 | 2.5–20× | 12.5° × 9.4° FOV

The H35's larger 640×512 sensor contains substantially more thermal pixels and allows the same 35mm focal length to deliver a much wider field of view.

The L35, however, starts at a higher 4× magnification and costs less, making it a strong choice for customers who prioritise image scale and reach over maximum field of view and sensor resolution.
