Spherometer (50mm)
Product Code : JC-SL-4734
The 50 mm spherometer (SKU JC-SL-4734) measures the radius of curvature of spherical surfaces such as lenses and curved mirrors. Its disc and scales are lacquered brass and its legs are steel, painted black. The central screw is turned until it touches the surface, and the readings of the disc and scale give the height used to calculate the radius.
