45-686 200 mm Dia. Borofloat33 Protective Flat Window; t=6.5 mm Uncoated

The 45-686 is a 200 mm diameter, 6.5 mm thick uncoated Borofloat33 protective flat window, available from Edmund Optics. This window is a type of flat window, designed with a base shape of a circle, making it suitable for a wide range of applications.

The window is made from Borofloat33, a material known for its excellent optical properties and durability. Borofloat33 is a low-alkali glass, which makes it resistant to corrosion and chemical attack, making it an ideal choice for harsh environments. It also has a low coefficient of thermal expansion, which reduces the risk of thermal shock and makes it suitable for applications involving significant temperature changes.

The window has a diameter of 200 mm and a thickness of 6.5 mm, providing a robust and stable platform for optical systems. The uncoated surface ensures high transmittance across a wide range of wavelengths, with a specified wavelength of 587.6 nm. This makes it suitable for applications involving visible light.

The window is designed in the shape of a thin lens, which can help to minimize optical aberrations and distortions. This is particularly important in applications where high precision and accuracy are required.
