Laser Line Antireflection V-Coatings
Newport laser line V-coatings significantly increase transmission in laser systems with multiple optical elements. Through careful optimization, these durable, thin films reduce surface losses to typically less than 0.2%. Valuable laser energy is efficiently transmitted through complex optical systems rather than being lost to surface reflection and scatter. This superior performance, however, is achieved at the cost of reduced wavelength range. These coatings are available with many of the major laser lines. AR.33 for 1064 nm is available from stock on most Newport lenses. All other V-coatings can be coated on a semi-custom basis.
