| Narrow Band Beamsplitter Plate |
These type Beamsplitters are plate windows
coated with an all dielectric coating to
separate laser light into your choice of R/ T
split ratios. These Beamsplitters perform almost
no absorption and are designed specifically for
45¡ãat the wavelength and polarization being
used. Standard substrates have an AR coating on
the second surface and the parallelism is less
than 1 minute of arc.
