Rusan Thermal & Night Vision Clip-On Adaptors. The adaptor connects the HIKMICRO THUNDER 2.0 unit and the daylight scope. It supports M52 × 0.75 mm thread. Available sizes: 46, 47, 48, 52, 54, 57, 60, 64 and 65 mm.
Rusan Adaptors allows you to join your Thunder 2.0 thermal unit with a day-scope. It’s a throw-lever tensioning sleeve that threads onto the eyepiece end of the unit and slides over the objective lens housing.
The Rusan Adapter is a simple way of attaching a thermal clip-on device to your day scope’s objective. Simply slip it over the front lens of your scope and move the lever to the “clamp closed” position.
The adapter slips over approximately 35.6 mm of your objective lens so there is lots of clamping surface area for a great hold. The inside of the adapter is lined with a special film to provide for extra gripping power and assures a scratch free attachment. To determine the exact model, you need to measure the outside diameter of your objective lens at its end (in millimeters). The measurement needs to be exact so use calipers.
