ABSTRACT:
A phototypesetter has an optical path including a beam splitter intersecting the main light path and an auxiliary light path for reflecting the auxiliary light path into the main light path. An absorption element with a concave front surface is mounted behind the beam splitter to absorb the non-reflected light from the auxiliary beam. Additionally, the concave surface directs the nonabsorbed light to a light absorbent body.
