NOCPIX THERMAL MONOCULAR LUMI L35

The Nocpix LUMI L35 thermal monocular uses a 384×288 pixel sensor with ≤18 mK NETD and a 35 mm F0.9 objective lens, giving 4x base magnification and a detection range of up to 1800 m in a 143 mm, 335 g body. It is the LUMI for anyone who wants to see further without moving up to a higher-resolution sensor. Like every LUMI, it runs on a replaceable 18650 battery, records photo and video with sound on 32 GB and is IP67 rated.

Features

• 384×288 sensor at 12 µm with ≤18 mK NETD: a sensor developed in-house by Nocpix, running at 50 Hz, with the Reality+ (R+) image algorithm, which reduces noise and draws more detail from the sensor. Low NETD helps to separate the animal from the background on damp or low-contrast nights.
• 35 mm F0.9 objective lens: 7.5° × 5.7° field of view (13 × 10 m at 100 m) and 4x to 16x magnification. According to the manufacturer, the F0.9 aperture lets in about 20% more light than an F1.0 lens. Detection range of 1800 m for a 1.7 × 0.5 m target.
• 0.39-inch AMOLED display at 1024×768: eyepiece with 25 mm eye relief, a 10 mm exit pupil and −5 to +5 dioptre adjustment. Red and green palettes are designed to reduce eye strain, the image hue can be warm or cool, and brightness, sharpness and contrast have 10 levels each.
• Zoom, PIP and stabilisation: digital zoom in 4 steps (4x, 8x, 12x, 16x), a PIP window showing the centre of the image at 2x, electronic image stabilisation (EIS) and Ultra-clear mode, which boosts contrast in rain or fog.
• Replaceable 18650 battery: up to 4.5 hours of operation (measured at 22 °C with R+ on and Wi-Fi off). The battery fits either way round, which makes changing it in the dark easier, and the monocular can run from a 5 V power bank through the USB-C port.
• Recording and app: photo and video with sound on 32 GB of internal memory; connected to a computer by cable, it shows up as a storage drive. With built-in Wi-Fi and the NOCPIX app it streams the live image to a phone, controls the device, customises the buttons and updates the firmware.
• Compact and quiet: 143 × 47 × 74 mm and 335 g with battery, IP67 rated, works from −20 °C to +50 °C and has silent buttons so as not to disturb game.

Why choose this model?

The LUMI L35 has the same 384×288 sensor as the L19 but with the 35 mm objective: base magnification rises to 4x and detection to 1800 m. The field of view is narrower (7.5° × 5.7°, 13 × 10 m at 100 m), so it is better suited to open fields, crops and hillsides than to dense cover.

For the same range with more detail and a wider field, the choice is the H35 (640×512); to measure distances, the L35R, which is the L35 with a rangefinder.

How to choose

The LUMI series has four models without a rangefinder and two with one, all sharing the same display, eyepiece and battery. The P13 (256×192, 13 mm) and L19 (384×288, 19 mm) start at 2x and have a wide field of view, for short distances. The L35 (384×288, 35 mm) starts at 4x and detects up to 1800 m. The H35 (640×512, 35 mm) combines a wide field with more detail. The L35R and H35R are the L35 and H35 with a laser rangefinder up to 800 m and ballistic calculation. Rule of thumb: more pixels give more detail when zooming, and a longer objective gives more range but a narrower field of view.

Frequently asked questions

At what distance does the LUMI L35 detect an animal?
The manufacturer states 1800 m for a 1.7 × 0.5 m target. Detection means seeing that there is a heat source; recognising and identifying the animal requires much shorter distances.

What battery does the LUMI L35 use?
A replaceable 18650 battery, with up to 4.5 hours per charge at 22 °C. It fits either way round, and the monocular also runs from a 5 V power bank through the USB-C port.

Does the LUMI L35 have a rangefinder?
No. The version with a laser rangefinder up to 800 m is the LUMI L35R.

Does the LUMI L35 record photo and video?
Yes. It records photo and video with sound on 32 GB of internal memory. Files are copied to a computer over the USB-C cable, where the monocular shows up as a storage drive.

Can the LUMI L35 handle rain and cold?
It is IP67 rated against dust and water and works from −20 °C to +50 °C. Ultra-clear mode boosts contrast in rain or fog.

Can it be used during the day?
Yes. The manufacturer states that the LUMI series is designed for use at night and during the day, because the thermal image depends on heat, not light.
