DRIVER'S NIGHT VISION VIEWERS FOR ARMOURED VEHICLES
Theon Sensors has developed an extensive family of night driver's night vision viewers for several types of armoured vehicles. This is a biocular display viewer with an integrated Gen 2 or Gen 3, 25mm image intensifier tube that provides the driver with passive driving capability during the night.
With special-to-the-vehicle mounting bracket assemblies, the basic design can be fitted to almost any type of vehicle. The mounting assembly allows the viewers to rotate left and right with respect to a central detent position for surveillance when the vehicle is stopped, offering the driver an increased field of regard.
The driver's night vision viewers are powered either from the vehicle through a specific-to-the-vehicle power cable or from a 3V lithium battery. The battery needs not be removed while on vehicle supply with instantaneous switch-on of the lithium battery where the vehicle supply fails (eg. power supply cable failure).
NIGHT VISION WEAPON SIGHTS
Theon Sensors has developed a family of night vision weapon sights models NS-467C and NS-685C with 4x and 6x magnification respectively. Both night vision weapon sights are compact, lightweight, military standard, suitable for short, medium and long range surveillance and target engagement.
The Model NX-145A is a passive night driver’s viewer which fits into the centre M17 day vision block in the armoured vehicle.
The night vision weapon sights incorporate a red illuminated reticle that can be easily changed in the field without tools, thus allowing the use of the sights with different weapons in a fraction of time. After replacing the reticle, the sights retain their sealing and there is no need for nitrogen purging.
The night vision weapon sights incorporate an ELCAN Gen-4 mounting bracket assembly, that allows direct mounting on (MIL-STD-1913) picatinny rails, precise adjustment in elevation and azimuth and retention of bore-sighting under adverse military conditions.
CLIP-ON AFOCAL NIGHT VISION SIGHT
Theon Sensors has developed the NX-135B clip-on afocal night vision attachment for mounting on top of optical day sights and Laser Range Finders (LRFs) to provide night vision capability. It provides observation, target acquisition and aiming capabilities during night time or low light conditions by intensifying the available light of the nocturne sky.
The NS-467C night vision weapon sight with 4x magnification is fitted on the M4 carbine using the Elcan Gen-4 mounting bracket.
The NX-135B clip-on afocal is an add-on unit to optical day sights specifically designed for snipers and offering 24-hour operational capability.
The afocal night vision sight is mounted on top of the day sight via a dovetail mounting bracket interface. Due to its exact factory set 1X magnification, the sight mounts on Laser Range Finders (LRFs) and day sights without affecting their boresight settings. The user continues to operate the day sights as usually. Reticle readings, eye relief distances and shooting/observation practices remain the same as in day time.
The sight features the largest focal length objective lens in this class of instruments, thus providing increased recognition and identification ranges and a field of view which is a better match to the field of view of most LRFs and large magnification day sights.
Theon Sensors provides a range of products and services in optics design, IR assemblies, night vision, reflex and rifle sights.
