PRIRUČNIK ZA NVG - Vodič za kupovinu noćne vizije

FOM (Figure of Merit)

Formula: FOM = Resolution (lp/mm) × Signal-to-Noise Ratio (SNR)

A single number that summarizes tube quality. Higher is better.

Signal-to-Noise Ratio (SNR)

The single most important spec for real-world performance. SNR measures how clean the image is versus the random grain (scintillation). Higher SNR = cleaner image in low light. Every 1-2 points of SNR is noticeable. Prioritize SNR over resolution when choosing a tube.

Resolution (lp/mm)

The ability to resolve fine detail, measured in line pairs per millimeter at the center of the image. Higher resolution lets you identify targets at greater distance. 57+ lp/mm is good, 64+ is excellent.

EBI (Equivalent Background Illumination)

The "noise floor" — how much internal light the tube produces with zero input. Lower is better. Below 1.5 × 10⁻¹¹ lumens/ft² is excellent. Matters most in complete darkness.

Halo

The bright ring around point light sources (street lights, flashlights). Measured in millimeters — below 1.5mm is excellent. Important for urban environments with mixed lighting.

Gain

Total light amplification factor. 40,000-80,000 fL/fC is standard. Modern tubes have automatic gain control (AGC) that adjusts to ambient light conditions.

How to Read Your Datasheet

When you receive your datasheet, check these in order:

1. SNR first — 22+ is good, 25+ is excellent
2. Resolution — 57+ lp/mm is good, 64+ is excellent
3. Calculate FOM — Resolution × SNR. 1,600+ is the target
4. Zone 1 blemishes — The center MUST be clean. Edge spots are acceptable
5. Bright spots — Worse than dark spots. A bright spot is a reason to request a replacement
6. EBI and Halo — Secondary but check they're within spec

Important: A tube with 60 lp/mm and 30 SNR (FOM 1,800) will look better in real use than a tube with 72 lp/mm and 22 SNR (FOM 1,584). Always prioritize SNR.

4. White Phosphor vs Green Phosphor

The phosphor screen determines the color of the image you see. It does NOT affect resolution, SNR, or FOM — only how you perceive the output.

Our recommendation: White phosphor (P45) for serious use. The improved contrast perception and reduced eye fatigue are worth the premium. For budget builds, green phosphor (P43) is perfectly functional.

5. Tube Manufacturers

AGM Global Vision

AGM manufactures its image intensifier tubes under its own specifications and quality requirements. Their tubes are classified as Gen 2+ under the US system, and top-tier AGM tubes rival Gen 3 performance. AGM classifies tubes into the following grades:

• NL/NW (Level 1 & Level 2): FOM 1,000-1,600. Solid performance grades, available in green (NL) and white (NW) phosphor.
• AP (Advance Performance): FOM 1,600-2,000. High-performance grade with auto-gating. Comparable to low-to-mid Gen 3.
• HPW (High Performance): FOM 1,800-2,300+. Top tier. Comparable to mid-to-good Gen 3. Auto-gating standard.

Key advantage: No ITAR restrictions. AGM tubes can be freely purchased and shipped within Europe without export licensing.

Photonis (France/Netherlands)

European manufacturer of image intensifier tubes, known for their Gen 2+ technology. Photonis produces tubes under designations like SuperGen, 4G, and ECHO. No ITAR restrictions apply to their European-manufactured tubes.

L3Harris & Elbit Systems (USA/Israel)

Premium Gen 3 manufacturers (FOM 2,000-2,800+). However, their US-manufactured tubes are ITAR-restricted — importing them to Spain or most EU countries requires special government licensing that is extremely difficult to obtain for civilian use. For European buyers, AGM Gen 2+ devices are the practical choice.

6. PVS-14 Monoculars — The Gold Standard

The AN/PVS-14 is the most popular NVG format worldwide. A monocular design that mounts to a helmet, weapon, or can be used handheld. It leaves one eye unaided, which helps maintain ambient awareness and depth perception.

AP Tier (FOM 1800+)

Our highest-performing PVS-14 monoculars with AP-grade tubes. FOM 1,800-2,300+, the best available without ITAR restrictions.

Level 1 Tier

Excellent performance with AGM NL/NW grade tubes. The best value for money — ideal for getting into serious airsoft/milsim night vision.

Level 2 Tier

Entry-level tubes. Good performance at the most accessible price point for a genuine NVG.

7. PVS14-51 — Široko polje gledanja (51°)

Modeli PVS14-51 nude šire polje gledanja od 51 stepen u poređenju sa standardnim 40° kod klasičnog PVS-14. Ovo šire FOV omogućava p bolju situacionu svesnost — ključno u airsoftu i milsim (vojna simulacija) igricama gde periferni vid ima značaj.

8. Binokularni NVG — NVG-40 i NVG-50

Binokularni NVG koriste dve cevi za pojačavanje slike — po jednu za svako oko. Prednosti su značajne:

• Percepcija dubine: Binokularni vid omogućava prirodno procenjivanje udaljenosti
• Šire polje gledanja: Dva preklapajuća slike stvaraju širi vizuelni ugao
• Smanjen umor očiju: Obe rade zajedno umesto da samo jedna obavlja sav posao

Trgovanje: koštaju oko dvostruko više od monokulara (dve cevi) i teži su.

NVG-50 (Širi kućište)

NVG-40 (Kompaktno kućište)

9. PVS-7 zaštitne naočale

PVS-7 je dizajn zaštitnih naočala s jednom cijevi gdje oba oka gledaju istu sliku kroz ugrađeni dihotomni razdjelnik. To vam daje biokularno iskustvo (oba oka vide istu sliku) iz jedne cijevi – po nižoj cijeni od dvostrukih binokulara.

10. Wolf serija — NVG osnovni nivo

Wolf serija od AGM-a nudi pravi noćni vid po najpristupačnijim cijenama. Wolf-14 monokular počinje ispod 2.400 € – najpristupačniji način da uđete u svijet pravog noćnog vida.

11. FoxBat Bi-okulari — Opservacija na velikim udaljenostima

Serija FoxBat su uvećani bi-okulari dizajnirani za opservaciju na velikim udaljenostima u noćnim uslovima. Dostupni sa uvećanjem 5x i 8x, idealni su za izviđanje, pozicije pokrića i prepoznavanje ciljeva na daljinu.

12. Digitalna noćna vizija

Digitalna NV koristi CMOS senzor umesto cijevi za pojačanje slike. Prednosti: niža cena, mogućnost snimanja video zapisa i prikaz u boji kod nekih modela. Mane: niža real-time performansa u odnosu na analogne cijevi, blago kašnjenje slike i zavisnost od baterije.

Sionyx Aurora serija

Sionyx Aurora je digitalna kamera za noćnu viziju odlična za snimanje i neformalnu opservaciju. Nije zamena za analogne NVG za taktičku upotrebu, ali je savršena kao sekundarni uređaj ili alat za snimanje.

AGM Neith — Digitalni nišani i dodatni okviri

Serija Neith nudi digitalnu noćnu viziju u formatu puščanog nišana i dodatnih okvira. LRF verzije imaju ugrađeni laserski daljinomer.

13. Kacaig i pribor za kacige

Da biste koristili noćni vidnik (NVG) na kacigi, potrebna su vam tri komponenta: kućište (osnovna ploča na kacigi), držač (zglobna ruka) i J-ručka (povezuje držač sa NVG-om). Takođe vam je potreban kounter-težina na zadnjem delu kacige za balansiranje težine.

Wilcox-stil držači

L4 G24 je industrijski standard. Poseduje mehanizam za odvajanje koji se odmiče pod udarcem kako bi zaštitio vaš vrat. G19, G30 i L2G05 nude različite profile i raspone podešavanja.

Profesionalni AGM držači

Autorizovani AGM držači za profesionalnu/militarnu upotrebu. Veća kvaliteta izrade i kompatibilnost sa MIL-SPEC standardima.

Držači za oružje

Montirajte svoj NVG direktno na pušku za konfiguraciju noćnog nišana montiranog na oružje.

Kounter-težina

PVS-14 na kacigom držaču teži oko 400-500g visi na prednjem delu. Bez kounter-težine, vaš vrat će se brzo umoriti. Koristite 200-300g na zadnjem delu kacige — baterijski paket, specijalizovana kounter-težina ili čak obična torbica sa rezervnim baterijama.

14. IR osvetljači

U veoma mračnim uslovima (bez meseca, unutrašnjost, gusta

15. Laseri i uređaji za gađanje (AN-PEQ / DBAL)

Lazeri za gađanje projektiraju točku IR lasera koja je vidljiva samo kroz noćne naočale (NVG), omogućavajući vam gađanje bez upotrebe nišana vaše puške. Mnogi također uključuju IR osvjetljivač. Za airsoft, replike uređaja tvrtke WADSN nude funkcionalne IR lasere po pristupačnim cijenama.

Preporučeni laseri

Naša preporuka: DBAL-A2 Aluminij nudi najbolju kvalitetu izrade s funkcionalnim IR laserom i osvjetljivačem. Za budžet konfiguracije, polimerski DBAL-A2 je savršeno adekvatan za airsoft.

17. Common Mistakes & Buying Advice

Mistake 1: Buying Gen 1

Gen 1 is fundamentally different technology. The image quality, weight, and durability are vastly worse. For any serious use, Gen 2+ minimum.

Mistake 2: Chasing FOM without understanding components

A tube with 80 lp/mm and 20 SNR (FOM 1,600) will look sharper on a chart but grainier in low light than a tube with 60 lp/mm and 28 SNR (FOM 1,680). Prioritize SNR.

Mistake 3: Buying without a datasheet

Every tube is unique. Never purchase without seeing the individual spec sheet. If a seller refuses to provide it, walk away.

Mistake 4: Trying to import US Gen 3

L3Harris and US Elbit tubes are ITAR-restricted. Importing them to Spain requires special government licensing that is extremely difficult to obtain for civilian use. AGM Gen 2+ AP and HPW grade tubes match mid-tier Gen 3 performance and are freely available in Europe.

Mistake 5: Forgetting accessories

Budget 300-800€ extra for: helmet, mount, J-arm, counterweight, IR illuminator, protective lens. The NVG alone is not the full setup.

Mistake 6: Not protecting the lens

For airsoft: always use a clear sacrificial lens in front of the objective. A 3€ lens protects your 3,000€+ tube from BB impacts.

Mistake 7: Expecting daylight vision at night

Even Gen 3 does not give you daylight-quality vision. In complete darkness you need IR illumination. Under starlight there will be grain. Manage expectations.

18. Maintenance & Care

Daily Use

• Always use lens caps when not actively using the device
• Never point at bright light sources — sun, powerful flashlights, and lasers can damage the tube permanently
• Use a lanyard when head-mounted to prevent drops
• Turn off before removing from helmet to avoid accidental bright light exposure

Cleaning

• Lenses: microfiber cloth + lens solution only. Never paper towels.
• Housing: damp cloth with mild soap
• Never open the housing — no user-serviceable parts. Opening voids warranty.

Storage

• Remove batteries during long-term storage
• Store in provided case with lens caps on, in a dark, cool, dry place
• Include silica gel desiccant packets

Batteries

Standard PVS-14 uses 1x AA battery. Lithium AAs recommended — they provide ~40-60 hours of use and perform better in cold weather. Always carry spares.
