Maximize Transmission
When light travels between media (for instance, glass and air), a portion
of the light is re ected – a phenomenon known as Fresnel Re ection.
Typical uncoated glass optical components will su er approximately 8
10% loss from Fresnel Re ections (depending on the wavelength of
light and the index of refraction of the material). Adding an antire ection
(AR) coating to the optical component can reduce that transmission
loss to 0.25% or less.
While an AR coating can signi cantly improve the performance of an
optical system, using the coating at wavelengths outside the design wavelength
range could potentially decrease the performance of the system.
Damage Threshold, Reference speci cations represent optics that
have had at least one laser induced damage threshold test performed on
a representative sample of parts for customer reference. For applications
that require a higher level of assurance in the published LIDT, please
look for optics containing a Damage Threshold, Certi ed speci cation.
