    							Appendix D 
    Throw Distance 
     
      Roadie 25K User’s Manual D-1 
    When planning a projector installation, consult this Appendix and/or use the Lens 
    Calculator available at the website. See also 2.3, Projector Position and Mounting. 
    Calculating Throw Distance 
    In this projector, throw distance is measured from the screen to the non-recessed 
    portion of the projector’s front bezel. Determining an ideal throw distance depends 
    on the screen size and lens present at your site—the larger the image needed, the 
    greater the throw distance required. Once you know the screen size and lens type 
    present, you can calculate the required throw distance by using the appropriate 
    formula provided on page D-2, or by looking it up in the Table for this lens. 
     
    This measurement (see above) is not necessarily parallel to the floor—i.e., the 
    projector and screen may be inclined. 
    NOTES:1) If your projector is tilted up or down in relation to the screen, typical in 
    large venues and/or elevated installation, throw distance still represents the smallest 
    measurement between the screen and front bezel. 2) Remember that throw distances 
    provided in this Appendix are calculated from the screen to the front bezel of the 
    projector rather than its foot centers. To figure throw distance from foot centers, add 
    8.74” (22.2 cm). 
    Table D.1 provides the throw distance formula for each lens. Once you know what 
    size screen you wish to fill, use the formula for the corresponding lens to calculate 
    the recommended throw distance. All formulas are in centimeters (cm). 
    NOTE: Minimum throw distance is 15 feet for all lenses except as noted.   Introduction

    Max: 8.71 x screen width (↔ cm) + 1.2 9m (30 ft.)  44m (145 ft.) 
    NOTES: 1) Make sure to use HORIZONTAL screen width in all formulas. 2) Throw distance can often be exceeded with negligible 
    loss of focus. 3) Throw ratios, formulas and throw distances apply to both standard and optional high-contrast lenses. 
     
    Based on the formulas provided in Table D.1, a selection of pre-calculated throw 
    distances for each lens type appears in the charts on the following pages. Refer to 
    these examples to quickly determine a proper throw distance (±5%) for your 
    installation and lens, or to determine what zoom range of image size is possible at a 
    given throw distance. 
    Keep in mind that ambient light, screen material, lamp size, image content and other 
    variables at your site may affect whether or not a given throw distance—and resulting 
    image size—will be ideal for your installation. 
    NOTE: Throw ratios, formulas and throw distances apply to both standard and 
    optional high-contrast lenses.
