Infrared (IR) and IR lasers in France: what the law actually says

The 30-second version. "Infrared" covers three distinct legal realities in France, and everything depends on which one you mean. Passive infrared (thermal imaging) follows the night vision device regime. A classic IR illuminator (LED) is not a laser: it is broadly free to buy and own. By contrast, as soon as you talk about an infrared laser (laser illuminator, designator, aiming laser), you enter the strict regulation of laser devices — and an IR laser, because it is invisible, is by nature more dangerous and more tightly controlled than a visible laser of the same power. Finally, a laser mounted on a weapon or a military designator shifts into war materiel (category A2).

This is the second most misunderstood legal subject in the field, after the classification of NVGs themselves — not least because the word "infrared" designates very different objects. This page sorts it out, with the texts to back it up.

Regulations evolve (article R311-2 was amended again in September 2025) and their interpretation ultimately rests with the administration and the courts. If in doubt, contact the Ministry of the Interior, the DGCCRF (for lasers) or a specialised lawyer.

1. The three "infrareds" you must not confuse

Before talking about the law, you must name the object precisely:

That is where the whole confusion comes from: filing these three objects under a single word "infrared" is like lumping together a thermometer, a lamp and a laser.

2. Passive infrared (thermal)

A thermal camera or monocular projects no light: it detects the infrared radiation (heat) emitted by the environment. As such, it follows the same logic as other night observation devices. Article R311-2 of the Internal Security Code, category A2, 14°, expressly targets materiel using « l'intensification de lumière ou l'infrarouge passif » (light intensification or passive infrared) when it is intended exclusively for military use or operated without the use of the hands (helmet-mounted).

In plain terms: a handheld thermal observation device, not intended for military use, falls under free possession, exactly like a light-intensification monocular. It is hands-free use and military purpose that tip it into war materiel. The full detail is covered on our dedicated page: Night vision goggle legislation in France.

3. The IR illuminator (LED): the legally simplest accessory

A classic infrared illuminator projects IR light invisible to the naked eye but visible to a night vision device, to "light up" a scene that is too dark. Technically, it is an LED (or a non-coherent source), not a laser.

Legal consequence: it does not fall under the regulation of laser devices, and it is not war materiel (it is neither an observation device, nor a laser, nor a designator). An LED IR illuminator is therefore, in the general case, free to buy and own in France as a night vision accessory.

Three common-sense caveats, nonetheless:

• Optical safety. Even without a laser, a powerful IR source remains subject to the general obligations of product safety and protection against optical radiation. A very powerful IR LED can pose a risk to the eye; manufacturers must comply with the applicable standards.
• Relative discretion. An active IR emission makes you visible to anyone who also has night vision. This is not a point of law, but it is an essential operational point.
• The "projector/designator" boundary. A device with a very concentrated, long-range emission, or with a designation/aiming function, may approach a more constrained regime (laser and/or A2). A diffuse supplementary illuminator is not concerned.

4. The infrared laser: the strict regulation of laser devices

This is where everything changes. As soon as you talk about an infrared laser — IR laser illuminator, designator, aiming laser — you fall under decree no. 2007-665 of 2 May 2007, amended by decree no. 2012-1303 of 26 November 2012, on the safety of emitting laser devices.

The principle. Laser devices of a class higher than 2 are prohibited for manufacture, import, making available, possession for sale and sale to the general public: their commercialisation is reserved for a limited list of professional uses set by the decree. Non-compliance is punishable by the fines for 5th-class petty offences (contraventions de 5ᵉ classe).

The decisive nuance for IR. The class system is based on visible light: class 2 only covers the 400–700 nm range, where the blink reflex protects the eye. An infrared laser is invisible (typically 780–1000 nm): it triggers no protective reflex, you don't even know you are exposed. As a result, an IR laser is never "class 2" and is, at equal power, classified higher and more restricted than a visible laser. In other words: most IR lasers useful for night vision fall beyond class 2, hence out of reach of the general public.

5. Weapon-mounted lasers and designators = war materiel

A weapon-mounted aiming/designation laser (functional PEQ/DBAL type) combines two constraining regimes:

1. The laser regime above (almost always beyond class 2 for IR designation use);
2. Classification as war materiel. Article R311-2, category A2, classifies in particular « matériels de pointage, de visée ou de désignation d'objectif destinés à l'usage des armes et matériels de cette catégorie » (pointing, sighting or target-designation materiel intended for use with the weapons and materiel of this category), as well as, at 3°, « armes auxquelles un rayon laser […] confère des capacités de mise hors de combat ou de destruction » (weapons to which a laser beam confers incapacitation or destruction capabilities) — dazzling/destruction lasers.

In practice, a functional military-purpose IR laser designator is not accessible to a private individual in France: prohibited for acquisition and possession except by authorisation (reserved for the State and approved bodies). Not to be confused with airsoft "PEQ/DBAL" replicas without a functional laser of a class higher than 2, which fall under an entirely different regime (toy/replica) — it is the presence of a real laser and/or a weapon-designation function that triggers the strict regimes.

6. Myth: "infrared means military, therefore banned"

False, and that's the trap. Legality does not depend on the word "infrared" but on the technology and the function:

• Handheld thermal observation imaging: free.
• LED IR illuminator: free.
• IR laser: strictly controlled (class > 2 = listed professional use).
• Weapon-mounted laser/designator: war materiel.

The same reasoning as for NVGs applies: it is not the "generation" nor the "military" label that determines the regime, but what the device actually does and how it is operated.

7. In practice: rounding out your night vision while staying within the rules

For legal, worry-free night observation:

1. Favour an LED IR illuminator if you need to add light in very dark conditions: it is the legally simplest accessory.
2. Avoid dubious "consumer" IR lasers: beyond class 2, they are prohibited for sale outside authorised professional use, and invisible hence dangerous to the eyes.
3. Do not consider any weapon-mounted laser/designator: that is war materiel.
4. For thermal, reason as for an NVG: handheld observation = free; hands-free or military use = category A2.

Our LNVM and LAB-NVS devices are light-intensification observation materiel; adding a supplementary IR illuminator falls, in the general case, under free sale. As always, we document our technical choices and our tubes with full transparency — including on the legal front.
