Interference Filter
| Commercial filters are
available with a half-power width of about an angstrom. If the back
layer is totally reflective, then the arrangement is called a
dichroic mirror, reflecting only the selected wavelength. These
devices are designed for normal incidence, and shift in wavelength
to shorter wavelengths if tilted. The interference filter is widely
used in selcective interference, laser systems and imaging optical
systems. |
