Know before you buy
This lens assembly uses a standard M28 x 0.75 screw-on thread. It is designed to attach directly to the objective lens housing of compatible monoculars and goggles.
The 3X lens provides a wider field of view of at least 11.5 degrees, making it better for scanning areas. The 5X lens offers higher magnification for long-range identification but results in a narrower field of view of at least 7.5 degrees.
No, the lens is built to be waterproof and fog-resistant, rated for submersion up to 1 meter for 30 minutes. It is designed to maintain high light transmission even in challenging environmental conditions.
The 3X lens adds 180g to your device, while the 5X lens adds 325g. You should account for this additional weight if you are mounting your device to a head harness or helmet.
This lens is compatible with optics that feature an M28 x 0.75 mounting thread. We recommend verifying your specific device's objective lens threading before purchase to ensure a proper fit.
