ThermTec Nord, a manufacturer of advanced optoelectronic devices, has released a new series of its thermal imaging sights: Vidar.
The Vidar series consists of eight compact devices with different parameters and features, all of which use high sensitivity NETD sensors (<25 mK) and 12μm pixel size. The image is refreshed at 50 Hz and displayed on an 0.39" OLED screen and a resolution of 1024x768 pixels. All models are equipped with Wi-Fi, as well as a photo and video recording capability that supports memory cards with a capacity of up to 64 GB.Thanks to advanced image calibration algorithms (NUC), these thermal imagers have been adapted to silent operation without the use of the shutter to ensure image is continuously displayed during shooting. They have are 6 color palettes, 7 different reticles and 5 autonomous profiles for different weapon or shooting ranges, as well as many additional functions, including the Picture in Picture mode, quick reticle zeroing or the ability to being connected to smartphones.
The devices are powered by replaceable lithium-ion batterries (2x 18350 or 2x 18500), which enable up to 10 hours of use. The Vidar series products meet demanding water resistance standards and are IP67 certified.
The new range of Vidar devices is divided into two categories. Models starting with the number 3: 335, 335L, 360 and 360L use a sensor with a resolution of 384x288 pixels. The presence of the letter L in the name means the presence of a laser rangefinder with a range of up to 1500 meters and a ballistic calculator supported by AI algorithms, which additionally has the ability to identify distinguishable object within the Imager's field of view. While the 335 and 335L models are equipped with a 35 mm (F1.0) lens, the situation becomes definitely more interesting for 360 and 360L models. As in other series of ThermTec thermal imagers (e.g. Ares), a dual lens system was used here: 20/60 mm (F1.0), which allows to change the focal length in two steps by turning the ring adjacent to the lens. Thanks to this, the user can conveniently survey an area using the 1.8x zoom and 13.1°x9.8° field of view, and then switch to the 5.5x mode (FOV 4.4°x3.3°) for better target identification and precise shoting.
Analogous distinction was adopted for the Vidar models from the higher series - starting with the number 6. Unlike their cheaper counterparts, they use a matrix with a resolution of 640x512 pixels. The 635 and 635L offer a fixed focal length (35mm, F1.0), while the 660 and The 660L is equipped with a two-stage optical zoom. Due to the differences in the size of the matrix, the base values and viewing angles are different. For 20/60mm (F1.0) models, they are 1.1x (FOV 21.7°x17.4°) and 3.2x (FOV 7.3°x5.9°).
The prices of the new series thermal imagers start at over 2,000 EUR for the 335 model and go up to around 4,000 EUR for the top-of-the-range Vidar 660L.
