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)
ƒ 40LP/cm 8:1 f=110 cm (1.5 kg, t=1.9 mm)
ƒ 40LP/cm 10:1 f=110 cm (1.8 kg, t=2.3 mm)
ƒ 40LP/cm 10:1 f=150 cm (1.8 kg, t=2.3 mm)
ƒ 40LP/cm 10:1 f=180 cm (1.8 kg, t=2.3 mm)
ƒ 40LP/cm 12:1 f=180 cm (2.1 kg, t=2.7 mm)
13.3 Checking the Grid Installation Angle
(1)
After the grid installation, prepare the “audit_grid.exe” for the grid installation angle. *The
tool is exclusively for CXDI-40G COMPACT. (Cannot be used with other models).
