Single and Dual Wavelength AR Coatings

*Low loss V-coatings
*Dual wavelength coatings
*Suitable for high power application

A single wavelength V-coating can provide reflectance less than 0.20% for 0°incidence at the chosen wavelength.

Part No.	Reflectance	Wavelengths Covered(nm)
VAR1	R≤0.2% for 0° AOI	355
VAR2	R≤0.2% for 0° AOI	488
VAR3	R≤0.2% for 0° AOI	532
VAR4	R≤0.2% for 0° AOI	632.8
VAR5	R≤0.2% for 0° AOI	808
VAR6	R≤0.2% for 0° AOI	1064
VAR7	R≤0.2% for 0° AOI	1310
VAR8	R≤0.2% for 0° AOI	1550

Dual wavelength AR coating is used to cover two wavelengths which are far away from each other. They are useful for optics which must transmit a visible alignment laser as well as a near IR process beam or for transmission of fundamental and first harmonic wavelength.

Part No.	Reflectance	Wavelengths Covered(nm)
DAR1	R<0.25% @ 373nm & R <0.5% @745nm for 0° AOI	373nm/745nm
DAR2	R<0.25% @ 532nm & R <0.5% @1064nm for 0° AOI	532nm/1064nm
DAR3	R<0.25% @ 808nm & R <0.5% @1064nm for 0° AOI	808nm/1064nm
