SAPPHIRE OPTICAL PRODUCTS

Sapphire has outstanding physical, optical, mechanical, thermal and chemical properties, along with superior radiation stability.

Sapphire products are ideal for the applications where high pressure, vacuum, or in corrosive atmospheres and are widely used in electro-optics, aerospace and bio-medical industries.

Typical uses for sapphire components are: -

Endoscopes and other medical optical applications. Infrared (IR) sapphire optics are used in laser systems. Sapphire is also used in micro lighting applications, and Sapphire Lenses and reflectors for fibre optics applications.

True Point (UK) Ltd can offer the following sapphire products: -

SAPPHIRE WINDOWS & DOMES

These high accuracy Sapphire windows are ideal for applications where high pressure, vacuum, or corrosive atmospheres and they are widely used in electro-optics, aerospace and bio-medical areas.

Advantages of using sapphire are: -

  • Extreme Surface Hardness and Chemical Resistance.

  • Is thinner and stronger than standard glass windows

  • Transmits wavelengths ranging from UV to Mid-Infrared.

  • The uncoated substrate is chemically inert and insoluble to water, common acids, or alkalis at temperatures up to ~1,000 C.

IPL LIGHT GUIDES & FILTERS



IPL light guides and filters are for IPL (intense pulsed light) machines.
We can offer surface quality of S/D: 20/10, and flatness λ/10

Light guides serve as the key element in cosmetic lasers, and intense pulsed light (IPL) applications. IPL is commonly used for the removal of unwanted hair, as well as a range of other cosmetic applications. IPL applications make use of a variety of wavebands to target different chromophores.
