Non-Polarizing Beam Splitter Cubes
|
Materials:
BK7 optical glass.
Consists of a pair of right angle prisms cemented with a
dielectric
coating on the hypotenuse of one prism.
Divides input beam into two equal parts: one transmits
without
minimal deviation, the other reflects at 90deg..
Two versions available: Narrowband (for laser lines) and
broadband.
