Convergence; Blemishes; Pixel Defects; Image Artifacts - Christie Mirage M Series Setup Manual

6.1.10 Convergence

Convergence zones A, B, C are as defined in Figure 2. Zone A has a diameter ¼ of the image height. Zone B has a diameter
of full image height. All specified convergence errors are between any two colors after a minimum warm-up of 30 minutes.
Convergence is specified with a 1.4-1.8 HD lens (part number 118-100112-01) in the 1.4:1 position with zero offset. Bore-
sight alignment must be adjusted for zero angular error. (Note: convergence error includes the effects of lateral color in the
projection lens. Measurements must be done on horizontal and vertical test pattern lines that intersect the center of the
image).

6.1.11 Blemishes

Blemishes are to be observed at 1 full screen height distance from the image for a period of 30 seconds. Screen size: 10 foot
wide for 350W models, 8 foot wide for 200W models. Blemishes are defined as per TI Specification 2506811.
