Lighting and Your Concrete Floor: An Unexpected Relationship

WebWhen testing for specular reflectivity, the laser and the sensor are moved to different positions symmetrically with respect to the central axis as defined by their pivot rod. An example of this setup is shown in Figure 2. By positioning iris diaphragms in front of both the laser and sensor, the diffuse scattering of the laser beam is minimized ... WebIn short, epoxy concrete floors are extremely versatile and almost infinitely customizable. Best of all, they are an environmentally friendly choice in several ways; for example, they increase light reflectivity by up to 300%, which means you can reduce the wattage or number of lights in your facility and save on your electricity bill.
