[QUOTE="takisot, post: 319961, member: 12"] Tα αντιστοιχο [B]Rogers report[/B] για τον [B]60[/B]ρη λεει τα εξης: At the zoom lens minimum throw ratio, the projector produced 957 lumens using Auto iris in the High lamp power mode. [B]But the maximum full-field (on-off) contrast ratios are obtained using the maximum throw ratio of the zoom lens. [/B]I measured 3,650:1, 4,970:1, 16,100:1, and [B]19,100:1[/B] in the Iris Off, Manual Iris (minimum aperture), Auto 2, and [B]Auto 1[/B] modes respectively. The High lamp power produced 682 lumens at the maximum throw ratio, which is equivalent to about 31.2 fL (foot-Lamberts) from my 85.3 x 48 inch, 1.3 gain, Stewart Filmscreen® StudioTek screen. I mounted the projector about 12.8 feet from my screen for viewing. At that distance (1.8 throw ratio) the projector produced 819 lumens using the Auto iris in the High lamp power mode, and 388 lumens using the Manual Iris (minimum aperture) mode. Thatʼs equivalent to about 37.4 fL and 17.7 fL on my screen. I used the Low lamp power mode, which reduced the light output by about 34 percent. The full-field contrast ratio measure 3,310:1, 4,630:1, 13,100:1, and 16,300:1 in the four iris modes. [/QUOTE]
