43-627 2.5 mm Dia. Sapphire Protective Flat Window; t=0.5 mm Uncoated

The 43-627 is a circular, flat window with a diameter of 2.5 mm and a thickness of 0.5 mm. This window is made of sapphire, a material with the chemical formula Al2O3, and is uncoated. Sapphire, also known as corundum, is a highly durable material with a hardness of 9 on the Mohs scale, making it highly resistant to scratching and abrasion. It also has excellent optical properties, including a high refractive index and low absorption, making it ideal for use in optical systems.

This window is designed to protect optical components from environmental hazards such as dust, dirt, and moisture. Its flat design ensures minimal distortion of the light passing through it. The window's uncoated surface allows for versatility in its use, as it can be used in a wide range of wavelengths without the risk of coating interference.
