BOROFLOAT® 33 & Optical Mirrors: A Union of Inspiration & Quality
The performance requirements for optical mirrors are extremely rigorous as slight deviations can have significant impacts on the outcome of specific performance. Thermal stability is a must if mirrors are used in environments subjected to temperature changes. Excellent surface quality combined with exceptionally high transmission and reasonable cost are other attributes that engineers consider when specifying their material of choice. BOROFLOAT® glass meets such demanding requirements and has been used for sophisticated optics around the globe.
BOROFLOAT® - The sum of its properties is what makes it unique for optical mirrors!
- Exceptionally high transparency
- Outstanding thermal resistance
- High chemical durability
- Broad range of sizes and thicknesses
Optical mirrors made of BOROFLOAT® glass offer outstanding transmission
BOROFLOAT®´s exceptionally high transparency, outstanding visual quality and optical clarity make it the material of choice for many optical applications in research and industry. High transparency in visible and near IR & UV range of wavelengths offers customers a vast wealth of new possibilities. Specific light transmittance values are thickness dependent and significantly influenced by Fe2O3 impurity levels. BOROFLOAT® specialty glass uses only the purest raw materials resulting in extremely low (~90 ppm) iron impurity levels and hence exceptionally high transmission values. In fact BOROFLOAT® is the industrial glass with the lowest level of iron impurity of all float glass materials in the market.
BOROFLOAT® glass - the ideal substrate for applications that require low inherent fluorescence
Some materials have the ability to emit electromagnetic radiation after being activated by high energy radiation. This property is referred to as fluorescence. It depends on the material’s purity and structural characteristics as well as the radiation’s excitation energy and excitation wavelength. BOROFLOAT® 33 is a highly transparent glass with a much lower inherent fluorescence than soda-lime flat glass.
Optics made of BOROFLOAT® glass are resistant to thermal loads and chemical attacks
The glass composition of BOROFLOAT® specialty glass is not only tailored towards excellent optical properties. It is also designed to provide very low thermal expansion and high chemical durability. The element boron plays a significant role in delivering such special properties as it determines how strong the bonds are within the glass network. BOROFLOAT® glass is used whenever very good temperature stability and excellent resistance to thermal shock are required. It can be thermally toughened and thermally shaped (3D). BOROFLOAT® is also highly resistant to hydrolytics, acids and alkalis and is known for its low alkali diffusion.
