Description of the Components:
An optical window is a flat, optically transparent material that is used to separate different physical environments while allowing light to pass through without altering its properties. Optical windows are crucial in applications requiring precise light transmission and are designed to be non-absorptive, meaning they do not change the light’s direction, polarization, or wavelength. They serve as protective barriers that prevent external factors, such as dust, moisture, and physical damage, from affecting the delicate optical systems housed within a device.
General Fabrication Specification:
- Materials: High-quality optical glasses such as SiO2, CaF2, BaF2, ZnSe, ZnS, Ge, and Sapphire are typically used, selected based on the specific wavelength and application.
- Dimensions: Ranges include diameters from Ø10 mm to Ø1000 mm, with thicknesses from 0.5 mm to 100 mm, depending on the specific requirements.
- Surface Quality: Achievable surface flatness up to λ/20 and surface quality up to 10-5 (scratch-dig).
- Tolerance: Dimensional tolerance within ±0.005 mm, with wedge angle tolerance up to 30″.
- Coatings: AR coatings, dielectric coatings, and other protective coatings are applied as needed to optimize transmission and minimize reflection across the desired wavelength range.
