Surmet continuously strives to develop novel, advanced optical ceramics products for current and future defense and
commercial systems. Using conventional powder processing techniques, Surmet has made substantial progress in its ability
to manufacture large ALON® sensor windows, lenses, domes and transparent armor. In addition to transparency, Surmet
has demonstrated the ability to incorporate other capabilities into its optical ceramic components, including: EMI shielding,
heating, internal antennas and cooling channels.
Working closely with the University of Rochester, Surmet has developed gradient index (GRIN) optics in ALON for
use in the visible through the MWIR applications. Surmet has demonstrated the ability to tailor the refractive index of
ALON® Optical Ceramic by either varying its composition or through the addition of dopants. Smooth axial and radial
gradient profiles with ~0.055 change in refractive index, over depths of 1-8 mm (axial) and over 20 mm radius (radial)
have been demonstrated. Initial design studies have shown that such elements provide unique capabilities. Radial gradients
in particular, with their optical power contribution, provide additional degrees of freedom for color correction in broadband
Surmet continues to mature ALON® GRIN technology along with the associated metrology. Surmet is committed to
the development of its ALON® GRIN capability as well as finding insertion opportunities in novel imaging solutions for
military and other commercial systems.
