WG80530 0.5in Dia. Silicon Broadband Precision Window; t=3 mm Uncoated

The WG80530 is a high-precision, flat window optical component manufactured by Thorlabs. This window is made of silicon, specifically silicon sal vil 1957, and has a base shape of a circle with a diameter of 0.5 inches or 12.7 millimeters. The window has a thickness of 3 millimeters, making it suitable for applications that require a thin, yet robust optical element.

The window is uncoated, which means it does not have any anti-reflective or other coatings. This can be advantageous in applications where the natural properties of silicon are desired, or where coatings may interfere with the optical path. However, it's important to note that uncoated windows can have higher reflectivity than coated ones, especially at certain wavelengths.

The window is designed to be used at a wavelength of 633 nanometers, although its properties may be suitable for use at other wavelengths as well. It has a shape similar to a thin lens, which can be beneficial in applications where focusing or collimation is required.

The WG80530 is currently in stock and available for purchase through Thorlabs' website. With its robust construction, precise dimensions, and high-quality silicon material, this window is an excellent choice for a wide range of optical applications.
