Professional Single Disk Spherometer — Apex Labs

The Apex Labs Professional Single Disk Spherometer is a high-precision metrology instrument specifically designed for measuring the radius of curvature of spherical surfaces, such as lenses and mirrors. Crafted from solid brass with a nickel-coated finish, this tool features a vertical main scale and a large, graduated micrometer dial for secondary readings. Its three-pronged base provides a stable tripod platform, while the central micrometer screw offers a fine pitch for exceptionally accurate vertical movement. This instrument is essential for optical workshops, physics laboratories, and engineering facilities.
