Perform the flange back value (f’F) adjustment after completing “4-4-3. Focus-Shift Adjustment”.

1)

Perform “4-4-1. Flange back (f’F) Check” and confirm that the flange back value (f’F) of lens to be checked does not meet the

specification in Table 4-4-1.

2)

Set the focus of lens to be checked to the infinite end.

3)

Viewing the microscope, turn the knob of flange back tester to focus.

4)

Using the formula below, calculate the shift amount (X).

Shift amount (X) = f’F (measured value) with focal length “24 mm” at the infinite end - 44.66 mm

X = Shift amount to be adjusted by the back washer

5)

According to the result in step 4), adjust the thickness of back washer

Measure the thickness of back washer with a micrometer (or a caliper). (Refer to Table 4-4-2.)

• In case of negative value (-) of shift amount (X), make the back washer thinner by x.

• In case of positive value (+) of shift amount (X), make the back washer thicker by x.
