White float windows are cost effective medium performance windows and acceptable in a host of scientific instrument applications. They are cut from large sheets that are relatively flat and parallel and can be supplied in standard thickness down to 1.1mm. Thinner windows can be supplied to special order. As no polishing is required white float windows are extremely economical. White float windows transmit efficiently from 320nm to 2600nm and are a good alternative to BK7 or equivalent . They are an economical choice of window as the substrate material is available in standard sheet polished material in a range of thicknesses so no polishing is required, unlike BK7 or equivalent that is originates as block material and requires further processing of sawing and polishing adding to cost. When using white float windows without antireflective coating there is a small residual reflection. If this is significant then the AR coated versions should be used.

We offer four versions of white float windows, uncoated, AR coated one face, AR coated both faces and ITO coated...
