12. Change the focal length and projection distance of the lens to be tested (in the case of zoom), and confirm that the number of projective
resolving power lines of the S image and M image meets the reference value at each focus and projection distance using the same pro-
cedure.
Reference value: Depends on each model. Refer to the service manual of each model.
13. If the reference value is not met in checking the projective resolving power, adjust the Lens Test Projector.
Note: The adjustment method and the reference value vary with each model. Refer to the service manual of each model to make the adjustment.
2-3. Finishing projective resolving power check
1. Click [Power] to turn off the power to the lens.
2. Confirm that the two LEDs on the B-L Control Box are not lit.
3. Click [Close] to disconnect communication between personal computer and B-L Control Box.
4. Click [Finish] to exit the program.
5. Turn the lamp switch of the Lens Test Projector to OFF.
6. When the Lens Test Projector is cooled down after several minutes, turn the fan switch of the Lens Test Projector to OFF.
3. FLANGE BACK CHECK
Equipments and Tools
• Flange back adjustment jig (J-6082-563-A)
• Siemens star chart (J-6080-875-A)
• Camera (NEX-5)
• 40 inch LCD monitor (Full HD)
3-1. Preparations
1. Set the siemens star chart on the flange back adjustment jig.
Note: Set the siemens star chart with the center to be 200 to 400 lux or 35 to 65 cd/m2.
For the siemens star chart, use a light source free from flickering.
2. On TELE end, set the distance from the lens of flange back adjustment jig to the lens to be tested to be within 10 mm.
3. Manually focus to make the center of the siemens star chart match with the center of the LCD.
4. Set the camera on the following mode.
Movie: AVCHD
5. Reset the lens to be tested. (Set the focus to be ∞)
* Do not touch the focus ring.

3-2. Capturing Image for Checking Flange Back
1. Capture a moving image of chart with the above settings.
Note: When a zoom lens is used, capture it while changing the focal distance arbitrarily.
Stop the zoom operation at each focal distance to capture the moving image.
3-3. Flange Back Check
1. Play back the movie captured in section 3-2 on a LCD monitor.
* Check that there is no notable image blur, center shifting, image shaking or image jumping.
