During this year's MSPO Warsaw-based presents two new products: ACRAB 2 integrated thermal-daytime sight and VIKI 1 thermovision sight.

ACRAB was developed in cooperation of Etronika with OBR SM Tarnów, under the project of Alex-338 8.6 mm x 70 sniper rifle – this one is seen here at MSPO on Alex-338 at Etronika stand. Below ACRAB 2 integrated thermal-daytime This sight that will have its premiere during MSPO

ACRAB was developed in cooperation with OBR SM Tarnów, under the project of Extended tactical range 8.6 mm x 70 (.338 Lapua Magnum) sniper rifle. For that reason the prototype was tested in late April at Nowa Dęba proving ground together with the Tarnów-built weapon. In result of the experience gathered during trial firings a new version of the sight was developed: the ACRAB 2. This is a device suggested for operations in rapidly changing scenery, such as sudden smoking. It is characterised by intuitive operation, and corrections in the thermal channel are coupled with corrections in the daytime channel. The thermal receiver is based on an uncooled bolometric matrix.

VIKI 1 thermovision sight. Small size allow using it with any weapon. It can also be used as a separate observation device. In VIKI 1 was used an athermal lens that provides sharp image within a broad range of temperatures without additional slide of the focusing elements

VIKI 1 is a thermovision sight for automatic rifles, fitted on a universal mounting rail. The device has a wide field of view at low magnification, so that the shooter can orientate himself in the area when searching for the target. As a rule, the soldier does not have much time to prepare for a shot, so the designers assumed the sight should be ready for action without the need for unnecessary operations. Calibration is intuitive, after the lens is covered. Additionally, information about its progress is displayed in the eyepiece. Thermal image digital processing capability has been limited to the basic functionality – there are only two pushbuttons in the body of the sight: one to switch between negative and positive image, and the other to switch on 2x electronic zoom.

The sight is activated by pushing any button, and deactivated by pushing both simultaneously (this happens after a while). Introduction of necessary corrections is done like in a classic sight: using a rotating scale.
