Description

Sapphire possesses nice light transmission in 0.*0 ~ 5.*0Î&frac*4;m wave band, and the infrared ray transmission is hardly influenced by temperature, so the optical components made of sapphire are fully applied to military infrared equipment, low-temperature laboratory viewing aperture, navigation and aviation high precise apparatus, etc. Specifications: Diameter: Φ1.*0 ~ Φ*5.*0mm Max deviation of diameter: 0.**3 ~ 0.*2 Thickness: 0.*5 ~ *0.*0mm, Max deviation of thickness: ±0.*1 Material: Synthetic sapphire single crystal(α-Al2O3≥*9.*9%) Orientation: C, A, R Axis Direction: C-Axis Deviation≤3° Surface roughness: Rz0.1 Flatness: λ/4ï&frac*4;š**3nm Center Deviation: 0.*1mm Surface requirement: polish on both sides Surface quality: S/D *0/*0; S/D *0/*0; S/D *0/*0 Infrared ray Transmission: when **3nm > *5% Please contact Antek Optics sales for detail.
