Sapphire Flats

Sapphire flatsSapphire's hardness and exceptional chemical stability make it superior to other glass and crystal materials for the protection of sensors and imaging systems that are used in challenging and harsh environments.

Sapphire is the choice of material for high grain and grit environments, where lesser windows and system covers deteriorate from chipping and abrasion.

Sapphire has a hardness of 9 Mohs and is chemically inert, ensuring that imaging and optical sensor systems are protected in flow analysis apparatus, harsh environment imaging and in high pressure systems such as oil flow analysis and pressure chambers.

Sapphire's broad transmission range make it ideal for a number of applications from UV, through Visible to NIR.

  • Windows

    Sapphire windows offer unrivaled hardness and wear ability, whilst also offering broad transmission fom UV to NIR wavelengths. Because Sapphire is a birefringent material, certain optical and sensor applications require the Sapphire material to be c-cut.

    Sapphire windows are used broadly in applications where high pressure or high resilience windows are required, such as underwater imaging and sensing, vacuum chambers and hazerdous environment imaging. Sapphire pressure windows offer thinner design possibilities and reduced scratch damage from flowing material or grit impact.

  • Wafers/Disks

    Due to its chemical inertness, resistance to process chemicals and its electrical proporties Sapphire is used for the processing of semiconducor GaAs, InP and silicon epitaxial growth.

    A-Plane Sapphire wafers are usually used for hybrid microelectronic applications requiring a uniform dielectric constant and highly isulating characteristics.

    C-Plane substrates are used for lll-V and 11-V1 compounds such as GaN for bright blue and green LED and laser diodes.

    R-Plane substrates are preferred for the hetero-epitaxial deposition of silicon used in microelectronic IC applications.

  • Plates

    Sapphire's high thermal, wear and volume resistance make it suitable for applications where the optical transmission is not necessary, protecting sensor systems or electronics from hazerdous environments. Replacing metal materials with ceramics and Sapphire may offer enhanced performance and reduced costs
