Chapter 2 Getting Started — Setting upENGLISH - 37Projection distance of each projection lensA ±5 % error in listed projection distances may occur.When [GEOMETRY] is used, distance is corrected to become smaller than the specified image size.For PT‑RZ770, PT‑RZ660r When the screen aspect ratio is 16:10(Unit: m)Lens type Standard zoomlensOptional lensFixed-focus Lens Ultra short focuszoom lensShort focus zoomlensProjection lens Model No. — ET-DLE030*2 ET-DLE055 ET-DLE085 ET-DLE150Throw ratio*1 1.7-2.4:1 0.38:1 0.8:1 0.8-1.0:1 1.3-1.9:1Projected image size Projectiondistance (L) Projectiondistance(L1)Distance betweenprojector andscreenProjection distance (L)Diagonal (SD) Height(SH)Width(SW)Min.(LW)Max.(LT) (L4) (A1) Fixed Min.(LW)Max.(LT)Min.(LW)Max.(LT)1.27 (50") 0.673 1.077 1.82 2.57 ― ― ― 0.83 0.82 1.04 1.38 2.011.52 (60") 0.808 1.292 2.20 3.10 ― ― ― 1.00 1.00 1.25 1.66 2.431.78 (70") 0.942 1.508 2.58 3.63 ― ― ― 1.18 1.17 1.47 1.95 2.842.03 (80") 1.077 1.723 2.95 4.16 ― ― ― 1.35 1.35 1.68 2.23 3.252.29 (90") 1.212 1.939 3.33 4.69 ― ― ― 1.53 1.52 1.90 2.52 3.662.54 (100") 1.346 2.154 3.71 5.21 0.82 0.11 0.43 1.70 1.70 2.11 2.81 4.083.05 (120") 1.615 2.585 4.47 6.27 0.98 0.28 0.53 2.05 2.05 2.55 3.38 4.903.81 (150") 2.019 3.231 5.60 7.86 1.23 0.52 0.69 2.58 2.57 3.19 4.24 6.145.08 (200") 2.692 4.308 7.50 10.50 1.63 0.93 0.93 3.45 3.44 4.27 5.67 8.206.35 (250") 3.365 5.385 9.39 13.14 2.04 1.34 1.18 ― 4.31 5.35 7.10 10.267.62 (300") 4.039 6.462 11.28 15.79 2.45 1.74 1.43 ― 5.18 6.43 8.53 12.338.89 (350") 4.712 7.539 13.18 18.43 2.85 2.15 1.69 ― 6.06 7.51 9.96 14.3910.16 (400") 5.385 8.616 15.07 21.07 ― ― ― ― 6.93 8.59 11.39 16.4512.70 (500") 6.731 10.770 18.86 26.36 ― ― ― ― 8.67 10.75 14.25 20.5815.24 (600") 8.077 12.923 22.64 31.65 ― ― ― ― 10.42 12.91 17.11 24.70Lens typeOptional lensHeight position (H)*3Intermediatefocus zoom lensLong focus zoomlensUltra long focuszoom lensProjection lens Model No. ET-DLE250 ET-DLE350 ET-DLE450 Standard zoomlens/ET-DLE085/ET-DLE150/ET-DLE250/ET-DLE350/ET-DLE450ET-DLE055(Fixed)Throw ratio*1 2.3-3.6:1 3.6-5.4:1 5.4-8.6:1Projected image size Projection distance (L)Diagonal (SD) Height(SH)Width(SW)Min.(LW)Max.(LT)Min.(LW)Max.(LT)Min.(LW)Max.(LT)1.27 (50") 0.673 1.077 2.42 3.87 3.80 5.81 5.66 9.12 0 - 0.44 0.341.52 (60") 0.808 1.292 2.92 4.65 4.59 7.00 6.85 11.01 0 - 0.53 0.401.78 (70") 0.942 1.508 3.42 5.44 5.38 8.19 8.04 12.89 0 - 0.62 0.472.03 (80") 1.077 1.723 3.92 6.23 6.16 9.38 9.23 14.78 0 - 0.71 0.542.29 (90") 1.212 1.939 4.42 7.02 6.95 10.57 10.43 16.66 0 - 0.80 0.612.54 (100") 1.346 2.154 4.92 7.81 7.74 11.76 11.62 18.55 0 - 0.89 0.673.05 (120") 1.615 2.585 5.91 9.39 9.31 14.14 14.00 22.31 0 - 1.07 0.813.81 (150") 2.019 3.231 7.41 11.75 11.68 17.71 17.58 27.97 0 - 1.33 1.015.08 (200") 2.692 4.308 9.91 15.70 15.61 23.66 23.54 37.39 0 - 1.78 1.356.35 (250") 3.365 5.385 12.41 19.64 19.55 29.61 29.50 46.81 0 - 2.22 ―7.62 (300") 4.039 6.462 14.91 23.59 23.49 35.56 35.46 56.24 0 - 2.67 ―8.89 (350") 4.712 7.539 17.40 27.53 27.42 41.51 41.42 65.66 0 - 3.11 ―10.16 (400") 5.385 8.616 19.90 31.48 31.36 47.46 47.38 75.08 0 - 3.55 ―12.70 (500") 6.731 10.770 24.90 39.37 39.23 59.36 59.30 93.93 0 - 4.44 ―15.24 (600") 8.077 12.923 29.89 47.25 47.11 71.25 71.22 112.77 0 - 5.33 ―*1 The throw ratio is based on the value during projection of 2.03 m (80") projected image size. When the Fixed-focus Lens (Model No.: ET-DLE030) isattached, the throw ratio is based on the value during projection of 2.54 m (100") projected image size.*2 When the Fixed-focus Lens (Model No.: ET-DLE030) is attached, the projection relation between the screen and the projector differs from that ofother lenses. Refer to “For the Fixed-focus Lens (Model No.: ET-DLE030)” (x page 34) for details.*3 When the Fixed-focus Lens (Model No.: ET-DLE055) is attached, the lens shift is not possible, therefore the height position (H) becomes SH/2.
