Cube Beamsplitters
Broadband cube beamsplitters, made from two identical right-
angle prisms cemented together, are ideal for separating a beam into
two components. The hypotenuse face of one prism contains the
beamsplitting coating. A small dot on the ground side of the prism indi-
cates which prism has the beamsplitting coating.
$Dielectric hybrid coating is relatively insensitive to
polarization; the broadband, all-dielectric coating
is sensitive to polarization. Both types provide a
nominal 50/50 split for unpolarized light.
$Cube construction makes them thermally and mechanically
stable.
$Cube beamsplitters are ideal for use with collimated or nearly
collimated beams
$All entrance and exit faces are antireflection coated.
