Liemke Thermal Optics is the embodiment of high-quality thermal night vision imaging. Based in Germany, our company is the market leader when it comes to image quality in thermal night vision devices for hunting. Our products range from handheld thermal imaging monoculars to thermal imaging pre-mounted devices for dual-use as a spotter or attachment to a riflescope and thermal imaging riflescopes. Handheld thermal night vision spotters, found in the Liemke KEILER and Liemke CHALLENGER series, are used to detect and observe game in difficult weather conditions such as in darkness and fog. Our Liemke MERLIN thermal imaging front attachments can be used as multifunctional or dual-use thermal imaging devices, either hand-held for observations or as an attachment in front of day optics. With the help of a clamping adapter, the MERLIN can be attached within seconds to the objective of the riflescope.
