43-629 9.5 mm Dia. Sapphire Protective Flat Window; t=0.5 mm Uncoated

The 43-629 is a circular, flat window with a diameter of 9.5 mm and a thickness of 0.5 mm. This window is made of sapphire, a material with the chemical formula Al2O3, and is sourced from the vendor Edmund Optics. The sapphire material is known for its excellent optical properties, including a high refractive index and high resistance to scratching and environmental damage.

This window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where maintaining the natural optical properties of the sapphire is crucial. However, it's important to note that uncoated windows may be more susceptible to environmental factors such as dust and moisture.

The window is designed to operate at a wavelength of 587.6 nm, making it suitable for use in a wide range of optical systems and applications. Its thin lens shape allows it to be easily integrated into existing optical designs.
