Thermal imaging device

for government and military

The Jahnke Thermal S thermal imaging attachment is our safe solution for government or military applications.

Thermal imaging device Jahnke Thermal S

For fast and accurate target acquisition of potential threats in governmental or military applications. The Jahnke Thermal S Clip-On offers optimum performance with a low operating weight of less than 400 grams and a length of only 15.2 centimeters.

Due to various limitations, which can only be compensated by great operational experience and training of the shooter – keywords spatial obstructions in the shooting sector or representation of the rear space – we give the Thermal S only in the hands of government agencies and military.


water protection class IP67 (submersible for short time)


35mm germanium lens


adapter socket (optionally available in individual sizes)


fast calibration time (588 milliseconds)

On-target combination of optics and thermal imaging

The Jahnke Thermal S Clip-On is connected directly to the optics of the weapon. Fixed via a suitable adapter, it is ready for use in seconds.

A VOx thermal imaging device (VOx is the abbreviation for: Vanadium Oxide) uses vanadium. This raw material is much rarer and therefore more expensive than the silicon often used in other thermal devices. Vanadium oxide has a better thermal conductivity than a thermal imaging device using silicon.

Details of the water protection level:

The IP code is defined according to IEC 529, EN 60529, DIN VDE 0470-1 and NF C 20-010 and designates the degree of protection against foreign bodies and contact and water of housings and covers. In the case of protection class IP67, this designates a product that fully protects the electronics or equipment against dust (IP67), heavy splash water and brief immersion (IP67).
