WebThe spherometer depends on the correct working of all the pressure sensors - there is more to go wrong. Interferometric methods are self correcting and self calibrating. Lastly, the 3cm error by itself sounds nasty, but needs to be thought of in the context of other lens parameters: it may not be that bad. WebFeb 11, 2016 · A spherometer is an instrument for the precise measurement of the radius of a sphere. The spherometer directly measures a sagittal. Since the spherometer is essentially a type of... WebApr 8, 2024 · Use a spherometer to measure the radius of curvature of the two lens faces r 1 and r 2. Use any standard method to measure the focal length of the lens f. Use the lens makers formula 1 f = ( n − 1) ( 1 r 1 + 1 r 2) to find the refractive index n of the lens.
