Full Product DescriptionProduct description
The M27 Unity Vision Periscope with PMMA (acrylic) optics is a lightweight, durable, and cost-effective vision solution designed for use in a variety of armored fighting vehicles. Utilizing high-grade polymethyl methacrylate (PMMA), the periscope offers a clear, non-magnifying (1:1) field of view, enabling vehicle crews to observe their surroundings with natural perspective while remaining safely protected inside the vehicle.
Compared to its glass counterpart, the PMMA version of the M27 significantly reduces overall weight, which can be beneficial in vehicles where weight savings contribute to improved mobility, fuel efficiency, or ease of handling. PMMA offers excellent optical clarity and impact resistance, making it well-suited for rugged environments and extended field operations. It also demonstrates good performance under a range of environmental conditions, including temperature fluctuations and exposure to UV radiation.
The M27’s design supports easy integration into standard vision blocks and allows for quick, field-level maintenance or replacement. Optional features, such as UV-protective coatings, tinted finishes, or ballistic overlays, can be added based on operational requirements. This version of the M27 is ideal for applications where weight, cost efficiency, and reliable visibility are top priorities without compromising overall durability.
