Plane Windows (PW) are most commonly used to separate two environments while still allowing light to pass through. They are intended for transmissive use and are parallel to equal to or better than five arc minutes. These windows are manufactured to a surface figure of λ/10 at 633nm, except where otherwise indicated. OptiSource Plane Windows are available as coated or uncoated components. To select a coating please see the coating offerings in our catalog; if your dimensions are not listed, please contact OptiSource Technical Sales for your non-standard prototype or OEM requirement: sales@optisourcellc.com
