36-571 15 mm Dia. AR Coated Sapphire Protective Flat Window; t=2 mm NIR II 750-1550nm

This product is a 15 mm diameter, 2 mm thick Sapphire Flat Window, offered by Edmund Optics. It is designed for use in the Near-Infrared II (NIR II) spectrum, specifically catering to wavelengths between 750 and 1550 nanometers.

The window is made from Sapphire, a material with the chemical formula Al2O3, and is known for its exceptional hardness, making it highly resistant to scratches and abrasions. This makes it an ideal choice for applications requiring a robust and durable optical window.

The window features Anti-Reflective (AR) coatings on both the front and back surfaces. These coatings are designed according to the standard NIR-II curve, which is specifically tailored for use in the NIR II spectrum. The AR coatings help to minimize surface reflections, thereby improving transmission and enhancing the overall performance of the window.

The window is shaped as a thin lens, which can be beneficial in certain applications where a flat window may not provide the desired optical performance. The lens shape can help to control and manipulate the light path, providing improved focusing or collimation capabilities.

The window is currently in stock and available for immediate purchase. For more information, please refer to the provided weblink.
