Irayusa Micro Objective Focus Assist

The Irayusa Micro Objective Focus Assist is a precision accessory engineered to streamline focus adjustment on iRay thermal imaging devices. Thermal weapon sight operators and hunters who depend on rapid target acquisition benefit significantly from this accessory, as manual focus can introduce lag during critical engagement windows. The focus assist mechanism eliminates inconsistency in eyepiece adjustment, enabling shooters to achieve crisp thermal imagery in seconds rather than fumbling with standard focus rings.

This accessory features a textured cat tail throw lever that provides positive mechanical advantage and tactile feedback during focus adjustment. The throw lever design reduces finger fatigue and increases control precision, particularly when operating in darkness or while wearing tactical gloves. Weighing just 0.19 lbs and measuring 3.5 x 2.5 x 4.75 inches, the Micro Focus Assist attaches directly to the iRay Micro objective assembly without requiring modification to the parent device. The compact profile ensures minimal sight picture obstruction and maintains the optical system's overall balance during extended use.

Law enforcement, military personnel, and civilian marksmen who operate iRay Micro thermal scopes will experience measurable improvements in target clarity and shot preparation time. The focus assist is particularly valuable in variable-distance scenarios—such as long-range hunting or tactical operations—where rapid focus transitions between targets are necessary. Installation is straightforward, with no tools required; the lever simply secures to the objective housing via the existing mount points on iRay Micro devices. This accessory is an essential upgrade for anyone seeking faster, more reliable thermal image acquisition.
