Image Intensifier Tube

These products are the heart of night vision devices. These tubes are responsible for amplifying residual light into visible light for the human eye. We recommend purchasing these products if you already have a housing or if you want to build your own night vision device. Additionally, if your budget is limited, we recommend purchasing a cheap housing or even 3D printing one and installing the intensifier tube in it. You will also need lenses.

The tubes come in 3 variants:

CLASS C
The basic product of the series, can come with or without auto-gating. Both variants have ABC (Automatic Brightness Control) It can provide decent image resolution (60lp/mm) and signal-to-noise ratio (starting from 22) with FOM starting from 1400 to 1600.

CLASS B
The upgraded product of the series, its FOM starting from 1600 up to 1800, using auto-gated power supply technology, with a wider dynamic range, can adapt to a variety of complex environment, in the case of changing external lighting conditions, to provide users with a more comfortable observation experience. The resolution starts from 60 lp/mm and the SNR starts from 25. As an example, some variants can have res 60 lp/mm and SNR 28.

CLASS A
The flagship product of the series, which adopts optical reflection reduction technology, with photocathode sensitivity of over 1000 μA/m and FOM from 1800 up to 2200, and features such as near-infrared enhancement and small halo to meet the needs of users in identifying targets under different environmental conditions. For this class, the SNR starts from 30 and the resolution from 60 lp/mm.

The products we sell are categorized as Gen 2+ according to the standard generation classification. However, the generation classification system is outdated. The photocathode of our Class B and Class A products is multi-alkali+arsenide (essentially a hybrid between Gen 2 and Gen 3). The SNR (Signal-to-Noise Ratio), resolution, EBI (Equivalent Background Illumination), photocathode sensitivity, and gain are very important to consider when buying a product.
