Only 4G can offer ultra-fast Auto-Gating, the smallest halo and unrivaled spectral range from ultraviolet to near-infrared. Gain the unfair advantage in the darkest nights, in all terrain and operations. How far can I see with my intensified night vision device (NVD)? This is the most common question asked by NVD users.

One of the most critical parameters for NVDs is the Detection/ Recognition/ Identification (DRI) range at various light levels.

The further distance the user can see, the better he can react as he will be the first to see. Thanks to continuous investment in Research and Innovation, Photonis is bringing Image Intensifier Tube performance to levels where it had never reached before. 4G Night Vision Revolution is bringing a 40% extra range of DRI than existing tubes available on the market (*).(*) tested by experienced end-user in actual theatres of operations

4G Technology is a set of capabilities described by minimum specifications of modern Night Vision to deliver to end-users the highest performance in all field conditions.

4G Night Vision standards are defined by:

An Extended Bandwidth of photon collection to deliver a consistently high image quality in all environments (from below 400nm to above 1.000nm)

A FOM (figure of merit being Signal to Noise Ratio times the Resolution: SNR* R) above 1.800

A Resolution always superior to 57 lp/mm even in the most polluted light environments such as urban areas or when entering a building where the light is suddenly switched on

A Halo size never larger than 0.7mm around the brightest objects seen in the image to provide the highest details around the light sources

4G NV Tubes are available both in 18mm and 16mm formats
