ABSTRACT:
A beam splitter employed in an optical disc player comprises a pair of triangular prisms which are combined and adhered together to form an integral rectangular prism. The thus formed beam splitter is positioned on a metal chip whose surface is substantially rectangular having adjacent two sides projecting upward. The adjacent lower surfaces of the beam splitter fit the upward projecting sides of the metal chip and an adhesion material is coated only on the half triangular region defined by the sides and the combining line of the prisms to adhere the beam splitter to the metal chip.
