Non-polarizing Beam Splitting Cubes (Cemented) Non-polarizing Beam Splitting Cubes (Cemented)

Material: BK7 optical glass
C
onsists of a pair of right angle prisms optically cemented with a
  metallic-dielectric hybrid coating on the hypotenuse of one prism
Divides input beam into two equal parts: one transmits
  without minimal deviation, the other reflects at 90 degrees.
  Splitter ratio ~ 1:1

Broadband
Suitable for low power, low energy applications
