Estimated from pixel pitch and lens focal length using the Johnson criteria (2, 8 and 13 pixels across a 0.5 m human critical dimension), clear air, 50 % probability. A model of the optics, not a measurement — real range depends on temperature contrast, humidity and the animal.

Nocpix LUMI L35R

Handheld monocular384-classLaser rangefinder

The Nocpix LUMI L35R is a 384×288, 12 µm thermal handheld monocular behind a 35 mm lens, with a built-in laser rangefinder. On the Johnson yardstick that is an estimated 729 m detection and 182 m recognition range for a standing person; Nocpix quotes 1,600 m detection. Its estimated detection range is longer than 30% of the 67 units here.

how much further the box reaches than a 2-pixel, 0.5 m criterion

One pixel of this unit sees 0.343 mrad (12 µm ÷ 35 mm). Two pixels across a 0.5 m human is 0.5 ÷ (2 × 0.343) × 1000 = 729 m. The box figure is usually computed against a person’s 1.8 m height instead, which is why it comes out higher. Full explanation.

What the spec sheet says

Read from the published specifications and this catalog’s own numbers — not from owner reports, which we have not collected for this unit.

For it

12 µm pitch — the 35 mm lens sees what a 17 µm core would need 50 mm to match
Published NETD of ≤18 mK, 8th-lowest of the 51 units here that publish one
Built-in laser rangefinder
Runs on 18650 cells you can swap in the field
IP67 sealed — survives immersion, not just rain
Detection claim is only 2.2× our estimate — one of the more conservative box figures here

Against it

384-class core — 1.7× less field of view than a 640 behind the same lens
Narrow 7.5° field for a scanner
Rangefinder but no ballistic calculator — the holdover is still yours to work out
Warranty terms not published
