Before Disassembly / Assembly / Adjustment ...

Note:

① When disassembling, make sure to memorize the processing state of wires and FPC.
② Because prototypes are used for "Disassembly/(Re)assembly/Adjustment", they may differ from the actual

products in forms, etc.

③ Because pictures are processed by a special method, they may differ from the actual ones in texture.

Points to notice for Lead-free solder products

・Lead-free solder is used for this product.
　・For soldering work, the special solder and soldering iron are required.
　・Do NOT mix up lead-free solder with traditional solder.

　・Use the special soldering iron respectively for lead-free solder and lead solder.

They cannot be used in common.

4-1:

In order to get necessary data for lens alignment, this board is created to use for setting a special chart
and light viewers (for chart illumination), while taking pictures of the special chart with a digital camera.

Prepare a board (760 x 880 x 20 mm) or 2 package cardboard boxes (size 2.33).
(Note) Because you have to cut out the shape to embed light viewers, choose package cardboard boxes
(size 2.33) or material which can be easily cut.

󳊎 ref. Fig. 1

As for the 1st flattened cardboard box (size 2.33), check the positions for embedding the light viewers,
and cut out the shape at 5 locations (shaded parts/size 154 x 245 mm) as shown below.

󳊎ref. Fig. 2

(Note) Cutting the shape slightly smaller than the actual size of viewers makes it easier to fit the
positions of viewers tightly.

How to create Setting board of "Lens alignment chart" and "Viewer"

Put the 2nd flattened cardboard box (size 2.33) and the above cut-out 1st cardboard together as one,
and fix them by taping at 4 sides.

󳊎 ref. Fig. 3

Then as for the 2nd flattened cardboard box, cut out the shape again by matching the cut-out size of 3-1
for each viewer. 󳆎󳆎

As shown above, when viewers are embedded, secure them with square pieces of Velcro tape (hook

Aberration compensation data writing adjustment

This adjustment uses the software which calculates the aberration compensation data according to the feature

・

of lens aberration and writes in EEPROM of the lens, in order to improve the accuracy of autofocus.

Note: This adjustment is necessary when the main PCB and/or each lens part (glass, lens chamber) is

replaced or when each lens part is disassembled. Be sure to make this adjustment after completing

inspecting and adjusting the main PCB.

① Prepare a camera (D100). Set the "Exposure mode" to "A" for full aperture and "Focus mode" to "S".

On the shooting menu, set the "Image quality mode" to "FINE", "Image size" to"L", "WB" to "Preset", and

"ISO" to "200".

② Set up the camera (D100), in which the lens to be inspected is t, on the tripod

200 mm, and the distance between the test chart and camera (CCD face) to 6 m 00±2 cm.

Resolusion inspection

At repair/service facilities where there is no projector, check the resolution by shooting the high-denition

resolution chart.

1. Check the resolution

By shooting the high-denition resolution chart (J63079), conrm that the TV lines are within the standard.

Standard for the TV lines:
WIDE (55 mm): 1200 or more TV lines in the center ; 1200 or more TV lines on the periphery /4
corners
TELE (200 mm): 1000 or more TV lines in the center ; 1000 or more TV lines on the periphery /4
corners

(ref. The unit of resolution is based on TV lines, which are total number of black-and-white strips
distinguishable on the TV screen.)

Device: D100 camera, ITE high resolution chart (J63079), icker-less uorescent (AAA)

(a) Camera settings: Aperture-Priority Auto (A), Shooting-mode (P), Image quality mode (FINE), Image

size (FULL), ISO (200), Image sharpening (None), Tone compensation (Normal)

Reset other settings (e.g. compensation) and shoot pictures.

(b) To avoid light irregularity on the chart, for either 2 units of Z light (Z-309)(J19124) or 2 units of 15W

inverter-type uorescent stand, use uorescent lamp color-rendering AAA (J19124A). Set them so that
reected light does not directly come in shot images.

As for exposure, open the shot images via PHOTOSHOP, and make an exposure compensation so that

the value of RGV becomes 219±10 LSB, when the cursor comes to white parts of the images.

(ref. : Set the exposure compensation to about +1-step for becoming 219±10 LSB.)

(c) Check the zoom position at WIDE and TELE.

The object distance: WIDE (approx.1.8m), and TELE (approx.5.4m). Set the chart fully screened in the
LCD of the camera and x it on a tripod. 
Because horizontal-to-vertical/aspect ratio is different between the chart and the nder eld frame, align
with the vertical direction (ref. Pic.1)

(d) Open the shot image by Photoshop, and conrm it by the magnied display, e.g. 100%, etc.　
(e) Check if the resolution in the center and the 4 corners is identiable in black and white at the position

circled in red as below.

(Refer to the next page for sample of defective image.)

2. Sample image: for judging the chart (on the periphery)

Shoot pictures of the chart. In case TV lines of the center become less than 1200 (WIDE) and less than
1000 (TELE), or any of the periphery/4 corners shows the following image of defective samples [less than
1200 (WIDE) and less than 1000 (TELE) TV lines], check that there is no damage to each part by shock,
etc, and then perform the lens alignment again on Page A14.

Note: For the judgment, the defective image sample should be prioritized over the number of TVlines.
