- Brewster Windows (BW):Brewster windows are used for large angles of incidence so that they present a circular cross section to the incoming beam at the Brewster`s angle. These windows are polished to a laser grade finish on both sides. Please contact the Lambda`s sales team for more coating information.
- Elliptical Windows (EW):Elliptical windows are used for large angles of incidence so that they present a circular cross section to the incoming beam. They are offered for use at 45° and at Brewster`s angle. These elliptical plane windows are polished to a laser grade finish on both sides. Select a coating appropriate to your application or contact us with your special coating requirements.
- Square Windows (SWI):These square plane windows are polished to a laser grade finish on both sides. They are intended for transmissive use and are parallel to better than 3 arc minutes. Select a coating appropriate to your application or contact us with your special coating requirements.
-
Wedge Windows (WW):These general purpose plane windows are polished to λ / 10 flatness except where indicated otherwise. Wedge windows are ideally design for beam sampling applications. Please contact the Lambda`s sales team for more information.
