SINGLE LAYER ANTI-REFLECTION (SAR)
Single Layer Magnesium Fluoride (MgF2)
is the most common anti-reflection coating. It is a hard, durable coating that reduces surface reflectance of BK7 from approximately 4% to less than 1.3% at the specified center wavele...
NARROWBAND ANTI-REFLECTION (NAR)
Narrowband Anti-Reflection coatings,
often referred to as “V”coatings, substantially reduce surface reflectance at the specified center wavelength and are better suited to laser applications than single-layer AR coatings. T...
BROADBAND ANTI-REFLECTION (BAR)
Broadband Anti-Reflection coatings
substanially reduce surface reflection over a broad spectral region. These coatings are less sensitive to angle of incidence than “V”coatings, which makes them well suited for the steepy c...
ND:YAG MULTI-WAVELENGTH ANTI REFLECTION (MAR)
Nd:YAG Multi-Wavelength Anti-Reflection coatings
substantially reduce surface reflectance at up to three YAG harmonic frequencies simultaneously. These all dielectric coatings are sensitive to polarization, wavelength and a...
