Product Description
Custom-made optical windows at any size from dia1.0mm to dia350mm clear aperture are available.
Optical windows are made of optical grade sapphire with plane parallel surfaces. They are used to admit light into an optical system and to protect it from dirt and moisture.
This sapphire window is treated with special heat treatment, making it far more intense than other materials, even the average sapphire material.
Therefore, this window is applied to flame detectors to prevent any flammable and explosive situations.
Product Family Description
- Features Extreme Surface Hardness Chemical Resistance
- Transmits Wavelengths Ranging From UV to Mid-Infrared
- Thinner and Stronger than Standard Glass Windows
HCH 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.
