All four faces AR coated and flat to λ/4
Inexpensive, yet effective for many beamsplitting requirements
Both transmission/reflection typically 25% - with 50% absorption
Standard cubes from 10 to 30mm

For white light applications where even
intensity splitting is required over a broad
wavelength region these simple cubes,
with metallic coatings, make an ideal
beamsplitter.
