The Radius Concave Lens Contact Ruler 7417 Convex Plate Contactometer is a precision instrument designed for measuring the radii of curvature of concave lenses and the thickness of convex lenses. This device is an essential tool for optical engineers, technicians, and researchers in the field of optics and lens manufacturing.
The contact ruler features a high-quality, durable concave plate made of hardened steel with a polished finish. The plate is precisely calibrated with a series of fine lines, each representing a specific radii of curvature value in millimeters. The ruler is designed to ensure accurate and reliable measurements, with a minimum measurement resolution of 0.01 mm.
The convex plate contactometer is attached to the concave plate, allowing for the measurement of the thickness of convex lenses. The convex plate is also made of hardened steel and has a polished finish. The thickness of the lens is measured by placing the lens on the convex plate and adjusting the height of the plate until the lens touches the plate evenly. The height of the plate is then read off the calibrated scale, providing the thickness of the lens.
The contact ruler is equipped with a sturdy base and adjustable legs, ensuring stability during measurements. The device also comes with a protective cover to keep the plate and convex plate clean and free from dust and debris.
The Radius Concave Lens Contact Ruler 7417 Convex Plate Contactometer is a versatile and reliable instrument that offers accurate and precise measurements for a wide range of applications in the field of optics and lens manufacturing. With its high-quality construction, easy-to-use design, and durable materials, this contact ruler is an essential tool for any professional in the field.
