Liemke Merlin-35 Adapter M52 (M43x0.75)

• M52 interface for MERLIN clip-on use: This adapter provides the correct connection between the LIEMKE MERLIN-35 and a KA-MC clamping adapter, making it possible to integrate the thermal device with a daytime scope setup.
• 360° rotational adjustment: The adapter can be aligned through a full rotation, which helps position the thermal clip-on level on the host optic for a clean, practical mounting arrangement.
• Three-screw alignment system: Fixing the adapter with three counter screws supports secure positioning and helps maintain consistent orientation once the device is mounted.
• Steel construction: A steel body gives the adapter the rigidity needed for repeated fitting and removal in field use, where a stable mechanical connection matters.
• Purpose-built LIEMKE accessory: Designed specifically for MERLIN-35 and MERLIN-25 thermal monocular and clip-on applications, it avoids the compromises that can come with generic adapter solutions.

About the Liemke Accessories Series

The Liemke Accessories series brings together the supporting components that make LIEMKE thermal devices easier to mount, protect and carry in practical hunting and outdoor use. Within the brand’s accessory range, the focus is on thermal camera accessories that solve specific integration tasks rather than adding unnecessary bulk. This includes mounting adapters for thermal clip-on devices and daytime scopes, protective flip covers, and carrying solutions for selected handheld units.

A clear example of this design approach is the KA-MC clamping adapter, which was developed to attach thermal clip-on devices to day optics with a slim profile and rubber-coated clamping surfaces. Across the series, LIEMKE emphasizes practical compatibility, secure attachment and straightforward handling in the field. The result is an accessory family aimed at users who need their thermal setup to work as a complete system, whether that means protecting an objective lens from dirt and moisture or creating the correct mechanical interface between a clip-on device and a riflescope.

About the Liemke Merlin-35 Adapter M52 (M43x0.75)

The Liemke Merlin-35 Adapter M52 (M43x0.75) is a dedicated interface component for users who want to run a MERLIN-35 or MERLIN-25 in combination with the LIEMKE KA-MC clamping adapter. Its role is simple but important: it creates the correct connection between the thermal device and the clamping adapter so the clip-on system can be mounted in front of a daytime optic in a controlled, repeatable way.

What makes this adapter especially useful in practice is its 360° adjustability. That rotational freedom allows the thermal unit to be aligned horizontally on the host optic before final tightening, which is important for a tidy setup and practical handling in the field. The three counter screws are there to lock that orientation in place once alignment is set, giving the user a secure mechanical fit rather than a loose or improvised connection.

The steel construction suits the job well because an adapter in this position needs stiffness and durability more than low weight. Finished in black, it matches the subdued appearance expected of hunting optics accessories. As a purpose-built LIEMKE part for thermal monocular and clip-on use, this adapter is best understood as a functional link in a complete mounting system rather than a generic ring: it is made specifically for the MERLIN platform and for use with the KA-MC adapter.

About Liemke

LIEMKE has been active in thermal imaging since 2008 and focuses on thermal imaging optics for hunting and outdoor use. The company expanded its technical base by developing its own optics since 2014, which is relevant for users looking at a brand with dedicated experience in this category rather than a general accessories maker. Its product portfolio includes the MERLIN thermal imaging line, while the KEILER range covers handheld devices and the LUCHS line covers pre-mounted thermal imaging devices.

In 2020, LIEMKE became part of the Blaser Group, linking the brand with a well-known name in hunting equipment. Across its thermal products, LIEMKE also supports image transfer to mobile devices through Wi-Fi or cable, showing the company’s emphasis on practical field use as well as optical performance.
