6. Reasons Why Lenses with Smaller Focal

Distances Cannot Be Measured

With the transmission type Centering measurement, focal distance “f” is a key factor for

measurement.

Finding the amount of eccentricity is effectively reading the

angle of deviation. If the angle is

identical between two lenses, the lens with a longer focal distance have a wider angle, which means

that its eccentricity can be read easily. (Obtain the resolution.)

is 1 minute

The minimum division in the eyepiece is 0.01 mm and lenses with a smaller feed amount than this

length cannot be measured in this device.

Therefore, a lens with a shorter focal distance will have a smaller feed amount and it cannot be

measured.
