Reflective optical sensors can generally be categorized into two types; light diffuse reflective and light convergent
reflective. The optical paths of both the emitter and the receiver in the light convergent type are narrower and more
angular than those of the light diffuse type. This optical convergent design can enhance its sensing ability for low-
reflective objects because of its high density light beam. The sensing area of the convergent type is thereby limited
as shown by the figures below.

B5W-LB Light convergent reflective type sensor User’s manual (E592)
The B5W-LB series is composed of light convergent reflective type sensors utilizing
Omron’s original optical lenses which are combined with 4-toroidal lens designs. These
sensors can provide stable sensing with a small amount of reflected light, and even black
paper and transparent plates can be detected in its wide sensing range. Furthermore,
the B5W-LB series will not detect any highly reflective background that is positioned
beyond the sensor’s sensing area.
