Subsea Optical Dome End-Cap
A precision-engineered optical dome manufactured from high-clarity polycarbonate under cleanroom conditions, for subsea imaging and vision systems. Its domed geometry minimizes image distortion and hydrodynamic drag versus flat acrylic caps, making it suited to wide-angle cameras and gimbal-mounted systems. Available exclusively in 115 mm diameter with a black anodized aluminum retaining ring.
