Installing The Grid; Overview; Notes - Canon CXDI-40G COMPACT Service Manual

13. Installing the Grid

13.1 Overview

Obtain a grid and fixture piece from a distributor, and install it on the Bucky unit, stand or table.
The grid is used as a fixed grid, and the grid vibrations are controlled if necessary.

13.2 Notes

1) Grid installation angle
The relative angular misalignment between the imaging unit sensor glass plate and the grid
±
must be 1.0°or less. For the checking method of the angular misalignment, see the next
section (13.3).
*Reference: The relative angular misalignment with respect to the imaging unit outer cover is
± 0.6° or less.
2) Selecting the grid
The recommended grids should be structurally identical to the recommended models for the
CXDI-40E series. The recommended grid specifications are shown below. Canon standard
grids that are set as options are identical to those in the CXDI-40E series.
*Grid density: 40 LP/cm±5% (Variation in line quantities per sheet is 1% or less)
*Dimensions: 448 mm (width) × 438 mm (height) × 1.5 to 3.8 mm (thickness)
However, this limitation does not apply due to the layout limitations of the Bucky unit.
*Grid constant: Compliant with the Canon optional grid.
*Reference: Canon optional grids (Grid constant)
40LP/cm 8:1 f=110 cm
40LP/cm 10:1 f=110 cm (1.8 kg, t=2.3 mm)
40LP/cm 10:1 f=150 cm (1.8 kg, t=2.3 mm)
40LP/cm 10:1 f=180 cm (1.8 kg, t=2.3 mm)
40LP/cm 12:1 f=180 cm (2.1 kg, t=2.7 mm)
13.3 Checking the Grid Installation Angle
After the grid installation, prepare the "audit_grid.exe" for the grid installation angle. *The
(1)
tool is exclusively for CXDI-40G COMPACT. (Cannot be used with other models).
