Boresight alignment procedure

INTRODUCTION

The following instructions outline Boresight Adjustment on any Roadster, Mirage, Matrix, DLV,

Christie DS and Christie DW model projector.

Boresight alignment ensures the projection lens is precisely parallel with the exit-face of the prism and

that the correct distance exists between the exit face and the input of the projection lens. Typically, this

procedure is performed whenever a lens mount is replaced to ensure the displayed image has optimum

focus in all four corners and the center.

Replacement must be performed by qualified Christie service personnel only.

NOTICE: Projectors must be serviced in a clean environment to prevent dust particles from settling on

optical components.

Lens cap with pinhole in center (Recommended, but not necessary).

Page 2 INSTRUCTIONS NOTE: For DLV1400-DX and DLV1920-DX models, refer to Boresight Alignment for Fixed Lens Mount Models, on page 3. 1. Set the spacing behind screws 1a, 2a, 3a and 4a to 4mm. Refer to Figure 1. 2. Load the “GRID” internal test pattern (Figure 3.
Page 3 You are now ready to perform a precision boresight alignment on the projector to achieve the best possible uniform focus. 1. Back off each corner locking screw (1b, 2b, 3b, & 4b) - refer to Figure 1). 2. Observe which portion of the image is out of focus. For example if the top left corner of the image is out of focus than you will need to adjust screw 3a until that point is correctly focused (see Grid Test Patterrn at right).
