RUSAN of Croatia now make an incredible 2.5x Monocular to attach to most thermal imaging devices. The 2.5x Magnification Ocular already includes an adapter to use with Rusan's Modular Connectors - these are unit specific and come in various sizes - see options on the drop-down.
Other than the 2.5x Magnification Ocular with included Adapter, you would need to correct Modular Connector with the corresponding thread size for your thermal imaging unit.
These connectors are used with the RUSAN MAR Connector required to mount the appropriate thermal imaging or night vision device.
Please select the appropriate connector from the menu.
Please Note: Delivery time is normally around 2 weeks from order date!!
***NOTE***
If your clip-on device does not have it's own counter nut, you need to buy a counter nut in appropriate thread size, except for these connectors:
MCR-M46: M46x0.75
MCR-M43: M43x0.75
MCR-M35: M35x1
MCR-M36: M36x1
MCR-TM35: Swarovski tM35
MCR-M52: Infiray MATE MAH-50 and others with 52mm thread
These above connectors already have a built-in system for orientation of the device, so no need for a counter-nut.
We can also order covers for these connectors, which keep the lenses of the thermal device safe and clean when the device is not in use.
For all connectors, the appropriate cover is MS-CON, except for connector MCR-M35 (Pulsar Krypton, Proton) which needs special cover MS-CON-M35.
