WHS2700 27 mm Dia. Sapphire Random Cut Round Window; t=2.5mm Uncoated

The WHS2700 is a 27 mm diameter sapphire random cut round window with a thickness of 2.5mm, uncoated and sourced from Knight Optical. This window is a flat, circular optical component designed for use in various applications where high-quality, durable, and transparent materials are required.

As a window, it is categorized under the 'Flat Window' subtype, indicating its planar geometry and minimal optical power. Its base shape is circular, making it suitable for applications requiring a circular aperture. The window's thin lens shape further ensures minimal optical aberrations and distortions, providing clear and accurate optical transmission.

The window is made of aluminum oxide (Al2O3) with the material ID 'mal-1972-n-o'. Aluminum oxide, also known as sapphire, is a highly scratch-resistant material with a hardness second only to diamond. This property makes the WHS2700 an excellent choice for applications requiring a durable and long-lasting optical window.

The window's wavelength of 633 nm suggests its intended use in red light applications. However, due to sapphire's broad transmission range (from UV to near-IR), this window can be used in various wavelength ranges.

The uncoated feature of this window implies that it does not have any additional layers of anti-reflective or protective coatings. While coatings can enhance the window's performance in specific applications, an uncoated window provides a cost-effective solution for general-purpose use.
