Optical Performance
The BL-2000 optic is designed for a typical total beam divergence of 70°, as shown in Figure 1. Total beam divergence is
the full angle measured where the luminous intensity is half of the peak value.
Figure 2 shows Illuminance for a BL-2000, 5500K white. These values have been calculated using the efficiency values of
the optic and the formula E = I / d
lens output and the measured point. Illuminance output depends on the luminous flux of the light source. The luminous
flux values for Lamina’s light sources are provided in the product data sheets.
