To select the appropriate lens for a front projection system, it is essential to request reflected ceiling plans. These plans provide a comprehensive view of the ceiling layout, including the positioning of lighting fixtures and other elements that can significantly affect the projection system's performance. Reflected ceiling plans allow you to assess the placement of the projector in relation to the screen and ensure that the lens chosen can accommodate the required throw distance and image size.

Moreover, reflected ceiling plans illustrate any obstructions or architectural features that might interfere with the projection, enabling a more informed decision on lens type, such as short-throw or long-throw lenses. This ensures optimal image quality, brightness, and coverage across the projection area.

While other types of drawings, such as electrical schematics and floor plans, provide useful information regarding the overall layout and power requirements, they do not offer the specific ceiling-related information necessary for lens selection relevant to front projection systems. Therefore, relying on reflected ceiling plans is critical for making the right choice regarding the appropriate lens.
