3)

Turn the mount rotation ring of lens test projector until the projected image at a certain peripheral point (y’= 9) on the screen appears

the most unsharp.

Read the number of the smallest pitched lines (both saggital and meridional: 3 lines) at the peripheral point.

**Note:**

When reading the number of the smallest pitched lines, be careful of the spurious resolution.

Spurious resolution is the reversed image of 2 or 4 lines which appears on screen when focus is beyond maximum revolving

power.

Do not confuse spurious resolution for the smallest pitched lines.

**Fig.4-3-4**

4)

Change the focal-length (zoom) and distance of the checking lens, and check that the all readings (y’= 0, saggital (S) and meridional

(M) at y’= 9) at each focal-length (zoom) and distance is within the specification of the Table 4-3-2.
