Wide observation angle reflective tape is a specialized form of retro-reflective sheeting that enhances visibility across a broader range of observation angles. Standard retro-reflective materials reflect light back towards the source in a relatively narrow cone, which can limit visibility for viewers at wider angles, such as drivers of taller vehicles like trucks. Wide observation films are designed to address this limitation.
How It Works:
Wide observation reflective tape disperses light more evenly across a broader cone of reflectivity. This is achieved using modified prisms within the tape, which are more angled and deeper compared to standard retro-reflective materials. The effect is similar to comparing a spotlight (standard reflective tape) to a floodlight (wide observation reflective tape). This increased dispersion means that more people at various angles can see the reflected light, enhancing safety and visibility.
For example, if you were to shine a pencil beam flashlight (analogous to standard reflective tape) into a crowd, only those directly in the beam’s path would see the light. However, if you replaced the pencil beam with a floodlight (analogous to wide observation reflective tape), a much larger portion of the crowd would be illuminated. This broader illumination makes it easier for drivers, especially those in larger vehicles or at different heights, to see signage and other reflective markers.
Available Brands:
Several brands offer wide observation angle reflective tapes. Notable examples include:
- Oralite 7900 Wide Observation Film: This is designed for applications where broader observation angles are critical. It ensures that signs remain visible from wider viewing distances and angles.
- Oralite 9900 All Observation Film: Another advanced product from Oralite, this tape is built to offer exceptional brightness while providing enhanced visibility from numerous angles. It’s particularly useful for traffic signage and other applications where visibility is paramount.
- 3M™ 400 Series DG3: An ultra bright film my the 3M company that returns a high percentage of light that is then spread out to create a bright and wider cone of reflectivity.
- Avery 11500 Omni Cube Wide Observation Reflective: A unique retro reflective film designed for signs, but also fine for a variety of other applications, especially when cut into rolls.
These tapes are particularly useful for traffic departments, road signage, and applications involving high and variable observation angles.
