Product Description
Night Vision Helmet Monocular IIT FOM1400 FOM1600 White Phosphor Image Intensifier Tube
High Resolution Image Intensifier tube Feature:
This image intensifier tube adopts double proximity focused electronic optical system and S25+ photocathode with extended near-infrared response and magnification ratio of 1. The product has the functions of strong light source protection and polarity reversal protection , and has the advantages of small size, light weight andd low power consumption.
There are 3 Class.
Class C
The basic product of the series, with technologies such as high-contrast optic fiber inverter and input enhancement, it can provie higher image resolution and signal-to-noise ratio with FOM1400 or higher, rendering superior image quality in low light conditions.
Class B
The upgraded product of the series, its FOM more than 1600, 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.
Class A
The flagship product of the series, which adopts optical reflection reduction technology, with photocathode sensitivity of over 1000u A/Im and FOM up to 1800, andd features such as near-infrared enhancement and small halo to meet the needs of users in indentifying targets under different environmental confitions.
