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

In addition to these standard parts, Newlight can
produce a wide variety of custom products. Please
contact us
for assistance for your custom requirements.
N-SF11, the RoHS version of standard SF11 may be used for the windows
without notice. N-SF11 will always be used for EU customers in
compliance with the RoHS regulations. Please let us know if N-SF11 and SF11 have to be
distinguished for your applications.
Coatings:
Various high quality HR, AR, Broadband AR (BBAR) and partial reflective (PR) coatings are also available
upon request.
AR Coatings: R<0.2% at the central wavelength
