coatings are offered to reduce surface reflections to a minimum.
Two types of broadband coating are offered. A single layer
of MgF2 on Fused Silica or BK7 reduces reflections per surface
to about 1.5% over a broad bandwidth. If lower reflectance
is required a multilayer broadband coating will provide an
average reflectance less than 0.5% per surface.
from single layer MgF2 broadband antireflective coating, the
multilayer Broadband antireflective coating can reaches higher
transmission for broadband spectrum. Therefore, it is the
ideal for a wide range of multi-wavelength laser and white
light application. Please notified that the wavelength range
and reflectivity of the coating are obviously changed according
to the incident angle.
