This is a 50/50 green laser beam splitter, non polarizing type. The 50/50 ratio changes with angle (50/50 at 45 deg) and with laser beam wavelength, shorter wavelengths are less reflected, and longer wavelengths are somewhat more strongly reflected, but is within 10% from 635 to 543nm. A nice optic for light show use to be sure.
