Description

AUTO-GATING is a special control electronics solution that is able to switch the tube on and off with a very high frequency, which is imperceptible by the eye. This innovative function allows the observer to operate in bright ambient light, or even in daylight operations. By keeping the full capability and performance, this function provides an efficient wear-protection of the device. Furthermore, this electronic solution eliminates the glare of the light source by maintaining the performance. Moreover, this function meets the high tactical requirements – for instance by operating under bright lighting conditions, such as military operations in urban terrains, that define many of today’s missions. This special control electronic solution prevents blinding and shadowing by various types of light sources or fire and helps to minimize the abrasion of the tube.


Features:

  • Automatic brightness control (ABC)
  • Bright source protection (BSP)
