1. Why choose the sapphire?
Thinner and Stronger than Standard Glass Windows
Transmits Wavelengths Ranging From UV to Mid-Infrared
Features Extreme Surface Hardness and Chemical Resistance
2. What is sapphire windows
Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.

√ Optical cemented lens are the simplest form of compound lens.
√ Optical glued lens consist of two elements of different refractive index, which are cemented together to provide a positive focal length imaging lens.
√ Optical glued lens are corrected for on-axis chromatic and spherical aberration making them good for broadband
√ Optical glued lens are supplied coated or with a single layer anti-reflection coating suitable for the visible (400 - 600 nm) or the near infra-red (600 - 1200 nm).
√ A wide range of focal lengths and diameters are available. Please ask for sizes and focal lengths required as we can supply a wide selection of Optical glued lens
