The BX2 Series of edge-lit backlights provides a highly diffuse source of illumination, packed within a thin and thermally efficient housing. The BX2 can be configured with polarization or collimation. A backlight configured with collimation is best suited for applications requiring a higher degree of edge clarity when imaging object silhouettes. This second edition of edge-lit backlights is more than twice as bright as previous BX and CX models. As with most planar backlight designs, this product is useful for edge detection, part location & orientation identification, presence & absence, hole detection, and object gauging.
