Falcon Sapphire
Falcon Sapphire is a Latvian manufacturer of monocrystalline sapphire and germanium optical components.
What is monocrystalline sapphire?
“Monocrystalline sapphire is a single-crystal form of aluminium oxide (Al₂O₃) — chemically identical to natural sapphire but grown in controlled industrial conditions. Its single-crystal structure gives it exceptional optical clarity, mechanical hardness (9 on the Mohs scale), and thermal stability — properties that make it suitable for precision optical, medical, and electronic applications.”
View in the company profileWhat is the Kyropoulos (KY) growth method?
“The Kyropoulos method grows large sapphire crystals by slowly cooling a molten alumina bath around a seed crystal. It produces some of the largest and highest-purity sapphire boules available — Falcon Sapphire produces boules of 100+ kg with exceptional optical homogeneity and minimal structural defects. KY is considered the leading method for demanding optical and precision applications.”
View in the company profileWhat purity grade do you offer?
“Our standard is 5N purity (99.999% Al₂O₃). We grow exclusively monocrystalline sapphire using high-purity alumina feedstock. UV grade and First Optical Grade are available for the most demanding applications. All material is grown within the European Union.”
View in the company profileWhat crystalline orientations can you provide?
“We supply sapphire in C-plane, A-plane, M-plane, and R-plane orientations to ±0.01° plane accuracy. Other orientations are available on request — talk to us about your specific requirement.”
