The Bausch & Lomb Optical Co. Rochester 7x50 (S/N: Not specified) is a legendary piece of American optical engineering, famously utilized by the U.S. Navy and maritime professionals for its uncompromising durability and low-light performance. Featuring a 7x magnification and large 50mm objective lenses, these binoculars are specifically designed to deliver a stable image and maximum brightness on moving vessels or in twilight conditions. Built with a heavy-duty, weather-resistant chassis and high-precision Porro prisms, the Rochester 7x50 represents the mechanical soul and optical clarity that made Bausch & Lomb the gold standard for long-range observation during the mid-20th century.

Key Features

• Professional 7x magnification optimized for stable handheld viewing in maritime environments

• Massive 50mm objective lenses for elite light-gathering capability and bright images

• Robust "Rochester" era all-metal construction built to rigorous military-grade standards

• Individual eyepiece focusing (IF) for surgical precision and superior weather sealing

• High-index Porro prisms providing an immersive, three-dimensional depth of field

• Textured "vulcanite" grip for secure handling in wet or cold conditions

• Oversized exit pupil (7.1mm) ensures a bright view even when the observer's pupils are dilated

Introductory Paragraph The Bausch & Lomb 7x50 is the definitive choice for the collector or outdoorsman who values structural integrity and optical brightness above all else. This specific unit represents a golden age of American manufacturing, where instruments were over-engineered to withstand the harshest oceanic environments. The 7x50 configuration is mathematically perfect for low-light use, providing a bright, clear image long after standard binoculars have faded to black. Because of its individual focus system, the binoculars are naturally more resistant to moisture and dust than center-focus models. Whether you are scanning the horizon from a boat or birdwatching in the deep woods at dawn, these Bausch & Lomb binoculars provide the mechanical precision and "heavy-duty" feel that modern lightweight optics cannot replicate.

Condition Report Good condition. The housing shows normal signs of light use and minor cosmetic surface wear consistent with its vintage age. The optics are clear, free from fungus, haze, or significant scratches. The internal Porro prisms are well-aligned, providing a comfortable single image without strain. Both individual eyepiece focus rings rotate smoothly with the correct amount of resistance. The bridge remains firm, and the textured grip is fully intact.

Specialist Note "The Rochester 7x50 is a 'tank' of the optical world. What I love about this model is the sheer brightness; it’s like turning the lights on in a dark room. The individual focus system is a hallmark of professional maritime gear—once you set it for your eyes, everything from about 25 yards to infinity is in focus. It feels incredibly balanced and substantial in the hand. For anyone seeking an honest, American-made instrument with a storied history and professional-grade performance, this Bausch & Lomb is an absolute classic."
