Protected Aluminum (PAL)
Protected Aluminum is the most commonly used metal coating for less
demanding, general purpose applications. As a front surface reflector,
aluminum is overcoated with one of several transmissive materials, depending
on the wavelength region of interest. As a back surface reflector, aluminum
is overcoated with a black epoxy paint. Protected aluminum is not sensitive
to wavelength, angle of incidence and polarization, so it useful for
a wide range of low power monochromatic and polychromatic applications.
Durability meets MIL SPEC requirements. |
