Our Crystals Empower Tomorrow's Technology
Fairfield Crystal Technology specializes in synthetic crystals growth and fabrication of the crystals into IR/VIS/UV optics.
Featured Materials
Calcium Fluoride (CaF2) is a naturally occurring optical substance with a unique range
of properties.
Calcium Fluoride 
Fairfield Crystal uses a unique source material purification with a vertical-Bridgman method to grow
synthetic high purity BaF2 single crystals.
Barium Fluoride 
Magnesium Fluoride is a tetragonal positive birefringent crystal grown using our,
proprietary source purification process with a vacuum Bridgeman technique.
Magnesium Fluoride 
Fairfield Crystal’s silicon windows (Si) are manufactured from optical grade silicon and are
designed to be used in precision optical systems for the 1.2 - 7μm spectral region.
Silicon 
Lithium Fluoride (LiF) is a cubic crystal that transmits very well into the extreme UV region at the hydrogen Lyman-alpha line (121 nm).
Lithium Fluoride 
Zinc Selenide crystals have a cubic zinc blende structure, similar to another compound
semiconductor like gallium arsenide (GaAs).
Zinc Selenide 
Zinc Sulfide exists in to main crystalline forms; more stable cubic form, known as zinc
blende or sphalerite and hexagonal form, known as the mineral wurtzite.
