47-542 75 mm Dia. Sapphire Protective Flat Window; t=2 mm Uncoated

The 47-542 is a 75 mm diameter uncoated sapphire window, boasting a thickness of 2 mm, making it an ideal choice for protective applications. Sourced from the reputable vendor Edmund Optics, this window is available and in stock, ensuring quick delivery for your project needs.

As a window, this component is designed to protect other optical elements from environmental factors, such as dust, moisture, or mechanical damage, while allowing the transmission of light. The 75 mm diameter provides ample surface area, suitable for a wide range of applications. The sapphire material, with the material ID al2o3 mal-1972-n-o, guarantees excellent durability and resistance to scratching, thanks to its hardness, which is just below that of diamond.

The window features a flat shape, ensuring uniform light transmission and minimal distortion. Its thin lens geometry further reduces the risk of optical aberrations, providing a clear and accurate image. The uncoated surface treatment allows for versatility in various wavelength applications, as it does not limit the transmission to specific spectral ranges. However, keep in mind that uncoated surfaces may lead to reduced transmission and increased reflectance compared to coated alternatives.

The 47-542 sapphire window is designed to work optimally at the wavelength of 587.6 nm, which is near the center of the visible light spectrum. This makes it suitable for applications in which visible light transmission is critical, such as imaging systems, optical sensors, and metrology instruments.
