|
Dichroic mirrors are longpass and shortpass filters that are used at non-normal angles of incidence. They highly reflect one specified spectral region while optimally transmitting another. Dichroics are available at all wavelengths, with reflectivity typically reaching values greater than 98% and transmission typically exceeding 85%. Dichroics are non-absorbing so that all light that is not transmitted is specularly reflected. |
