SF11 Windows/Rods

SF11 Windows/Rods

SF11 is dense flint glass with excellent chemical and physical properties. It has a good transmission in visible and near IR similar to BK7. But its higher index and dispersion makes it unique in fabrication of  lenses with minimized aberrations and prisms/windows/rods with large dispersions. In ultrafast optics, SF11 rods are commonly used as pulse stretchers due to its large dispersion.

Newlight Photonics offers circular/rectangular SF11 windows or rods with thickness from 0.15 mm to 150 mm. 

Various high quality HR, AR, and partial reflective coatings are available on SF11 faces.
