Thermal imager for the Eryx fire control sight Academic Article uri icon


  • Mirabel is a thermal sight developed for the Aerospatiale Eryx Weapon System. It is a `snap on' type sight which is attached to the weapon system's day sight. The system is lightweight (3 kg) with a recognition range of 1.2 km and boresight accuracy of 0.2 mR. Mirabel implements magnification one so it is not sensitive to interface accuracy between day and night sights. It provides for the use of the same eyepiece for both day and night usage, therefore allowing for human engineering optimization for both sights at once. The weapon system operates in both shoulder and tripod launch modes, and therefore imposes a very demanding human engineering consideration.
