A spherometer is used to measure the radius of curvature of a curved surface, such as a lens or mirror. It typically consists of three adjustable legs that can be used to determine the radius of the curved surface by measuring the height variation across the surface.

What is the unit of measurement in spherometer?

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 micrometer, it measures very small things like millimeters.

What is pitch of spherometer?

The distance moved my the screw in one complete rotation in the circular scale is called the pith of spherometer.


How are the pitch and least count of spherometer related?

The pitch of a spherometer is the distance between its tips when its central leg is displaced by one turn of the screw. The least count of a spherometer is the smallest distance it can measure, which is determined by the pitch of the screw. The least count is equal to the pitch of the spherometer divided by the number of divisions on the circular scale.

What do you mean by backlash error of spherometer?

when the three outer legs tilt or doesnt stand still,it's called backlash error in spherometer...


Why is zero error not considered in spherometer?

No, you have not any knowledge about spherometer. In spherometer also, similar to other measuring instruments zero error should be considered every time; in order to achieve accurate value.


How can you determine the least count of spherometer?

To determine the least count of a spherometer, you measure the total number of divisions on the circular scale and divide it by the total travel range of the micrometer screw. The least count is the smallest incremental distance that can be measured accurately by the spherometer.
