30mm Circular Optical Glass Lens Protector

The Sacrificial Lens Guard is a flat, optically clear polymer/glass protective window designed to protect primary objective lenses from physical impact, dust, scratches, and flying debris. Featuring a standard 30mm diameter circular design, this multi-use shield is compatible with standard commercial camera threads, microscope objectives, astronomy eyepieces, and hobbyist airsoft optics. Intended purely as an easily replaceable barrier to extend the lifespan of consumer glass optics. Compliance Note: This item is a low-technology, flat commercial lens protector. It features no military-grade anti-reflective coatings, lacks specialized military mounting hardware, and does not require integration into defense articles.
