At IWA 2023, we decided to stop by the ThermTec Nord company’s booth. We’d heard quite a bit of good news about them and wanted to see their products firsthand. The brand is owned by Dimeka Ltd which distributes ThermTec Nord products throughout Northern Europe. Their main product line consists of thermal imaging and night vision devices. In this article, we’re going to explore their Vidar series which comprises thermal imaging riflescopes.
The Vidar series introduces eight distinct models, divided into two categories: the standard Vidar series and the Vidar LRF series. The standard Vidar series includes Vidar 335, Vidar 360, Vidar 635, and Vidar 660, while the Vidar LRF series comprises Vidar 335L, Vidar 360L, Vidar 635L, and Vidar 660L. Models with a ‘3’ at the beginning are equipped with a 384×288 pixel sensor. In contrast, models starting with ‘6’ contain a 640×512 pixel sensor. Vidar 360, Vidar 660, Vidar 360L, and Vidar 660L uniquely possess the dual zoom feature which we will discuss in greater detail in the following paragraph.
Dual lens system
The dual zoom feature, found exclusively in the Vidar 360, Vidar 660, Vidar 360L, and Vidar 660L models, offers a unique capability; the users can transition between a 20mm lens and a 60mm lens by simply rotating the ring adjacent to the objective. Each lens provides a different base magnification, mimicking the effect of an optical zoom. It should be noted that the devices can only be used at the two base magnifications, the magnification range that lies in between is not usable. This system allows users to first scan the environment with the 20mm lens and then delve into the detailed examination with the 60mm lens. In terms of specific magnification, the 360 and 360L models provide base magnifications of 1.8x and 5.5x respectively. Meanwhile, the 660 and 660L models offer base magnifications of 1.1x and 3.2x.
The ‘L’ models
As previously highlighted, the Vidar series models marked with an ‘L’ are equipped with a laser rangefinder that includes a ballistic calculator feature. This advanced function provides a holdover at a specific distance based on the ammunition being used, thereby greatly enhancing the convenience and ethics of long-distance hunting by minimizing the risk of merely grazing an animal with a bullet. The laser rangefinder provides a measuring distance of up to 1500 meters.
Other noteworthy features
Vidar riflescopes are encased in a compact waterproof body. Models without the dual lens system measure 160 mm in length – they are similar in size to an average smartphone. The dual lens models are slightly longer, measuring 220 mm. All of them boast a shutterless calibration feature, where the shutter remains open during calibration – no noise is heard during the process. Powering these devices are two replaceable 18650 batteries which offer an impressive battery life of up to 14 hours and can be conveniently replaced in a couple of seconds. Vidar riflescopes come fitted with a 12-micron sensor that boasts a NETD of less than 25 mK. This allows the devices to discern extremely subtle temperature variations, a feature that proves particularly beneficial in conditions like rain or fog. The AMOLED display has a resolution of 1024 x 768 pixels. Users of the Vidar riflescopes have the option to choose from six different color modes. In addition to capturing images and recording videos, these devices can be paired with the Smart Thermal smartphone app, opening up a range of advanced features including image projection. All recorded data is conveniently saved to the device’s substantial internal memory, which offers a capacity of 64 GB.
The Vidar thermal riflescopes offer a multitude of sophisticated features. The first notable attribute is the wide array of models available, catering to various preferences and budgetary requirements. The dual lens models stand out due to providing two base magnifications that ensure a combination of rapid detection and detailed identification. The price ranges from 2000 € to 4500 €, depending on the model.
